Cancellation of hormonal pills in the middle of the cycle. Cancellation of oral contraceptives: what happens to my body. How to stop taking birth control pills correctly

Your tadpole is gradually becoming more and more like a small baby. From the 13th week of pregnancy, mostly his body will grow, so that by the end of pregnancy he will become five times larger than his head.

Fetus at 13 weeks of gestation: gender, weight and dimensions

The future baby already knows a lot: he smells the food his mother eats, sucks his thumb, tumbles, moves his arms and legs, opens and closes his fists. Start communicating with your child: he hears you, feels pain, responds to stimuli, reacts to changes in temperature and lighting, and even smiles, frowns, yawns! And how good he feels in his mother’s tummy: the muted twilight, warmth, softness, comfort, and the muffled sounds coming from afar are so soothing!

At the 13th week of pregnancy, the digestive and skeletal systems are most actively developing, “sketches” of the first ribs have already been made, and bone tissue is laid in place of the limbs and head. All 20 baby teeth of the baby have finally formed and will now wait in the wings. The placenta has completely taken over its functions. The pancreas began to produce insulin.

Sexual differentiation also occurs: in a boy, the prostate gland begins to develop, and the genital tubercle lengthens into the penis; in a girl, the ovaries located in the abdominal cavity descend into the pelvic area, and the genital tubercle bends downwards - the clitoris is formed from it. Surprisingly, girls’ ovaries are already filled with eggs: there are now more than 2 million of them!

A 13-week fetus weighs between 15-25 g and has an average “height” of 7-8 cm. It’s hard to believe, but this baby’s heart pumps 23 liters of blood per day!

Future mom

Meanwhile, your uterus grows rapidly, rising higher into the abdominal cavity, and gradually begins to press against other organs. More and more is pouring in. By the end of pregnancy, each of them will weigh from 400 to 800 g, and after childbirth even more. All your shapes are generally smoothed out and rounded, now your waist has disappeared, and your old clothes are clearly too small. Let's start pregnancy shopping!

Feelings at 13 weeks of pregnancy

Your health is already much better than before, anxieties and fears about the threat of miscarriage are gradually fading away, the fetus is actually safer than before and is subject to significantly fewer risks. But there is no need to relax. If you feel tightness in your lower abdomen, it is most likely due to stretching of the uterus, but it is better to play it safe and lie down until it gets better.

All the horrors of toxicosis are most likely a thing of the past, the nausea and vomiting have stopped, high spirits and the ability to enjoy life and future motherhood are returning.

The waist gradually becomes smoother and the belly becomes more and more visible. During this period, many women are already switching to a new wardrobe - “maternity clothes”. If this has not been done before now, it’s time to worry about purchasing comfortable, loose-fitting clothes, especially since old jeans and trousers probably no longer meet at the waist, and T-shirts and blouses treacherously fit the body.

By the 13th week, the problem of constipation may first appear: the muscle tone of the digestive tract is reduced, and on top of that, the uterus squeezes the intestines, worsening its peristalsis. Remember that taking laxatives during pregnancy is unacceptable! To avoid constipation and to regulate the frequency of bowel movements, you will have to pay special attention to your diet, as well as maintain physical activity.

Be sure to monitor your diet and ensure that all necessary substances are supplied to your body. Calcium is very important even at the 13th week of pregnancy, but it is better to give preference to plant sources: green vegetables, apples, persimmons, kiwi, lentils. If you have any problems, you should pay attention to this issue immediately.

Another very common problem during this period of pregnancy is headaches. The ban on medications is relevant in this case, therefore, we fight headaches using safe methods tested by time and experience. This is rest in a cool, dim, well-ventilated room, applying cool compresses to the temporal area, and, if possible, a short, restful sleep. In order to eliminate pain, it is also possible to take decoctions based on soothing herbs - lemon balm, mint, chamomile. But you shouldn’t get too carried away with mint: this herb has blood-thinning properties, which can contribute to bleeding. In cases where the headache is no longer bearable, a one-time use of paracetamol-based medications, for example, Efferalgan, Panadol, is acceptable. But taking painkillers that contain aspirin is strictly contraindicated during pregnancy.

Already now, without waiting for the active growth of the abdomen, mommy should take care of the issue of preventing the occurrence of stretch marks. Start using it. Risk areas: chest, abdomen, thighs, buttocks. It's time to take care of your beloved self. After all, now you are especially feminine and beautiful!

Belly at 13 weeks of pregnancy: tugs, hurts

And how much you don’t want to spoil this femininity and beauty by “the machinations of the body” in the form of increased gas formation and the inability to go to the toilet “for the most part”! It is problems with digestion and emptying that are perhaps not the first cause of abdominal pain at the 13th week of pregnancy. This means that in order to prevent them, it is better to study in advance what and in what quantities you can and should eat now. Eliminate from the diet, for example, black bread, legumes, raw cabbage, but at the same time drink a glass of decoction of prunes and dried apricots every day, do not forget about kefir and beets.

Abdominal pain may be associated with stretching of the ligaments holding the uterus. In this case, pain is observed on the sides of the abdomen, occurs from time to time, does not cause long-term inconvenience to the woman and does not pose any danger.

But if the stomach hurts and pulls, the pain is spasmodic in nature, the stomach seems to ache, most likely, we will talk about increased tone of the uterus. Perhaps the doctor will not see the need to immediately go to bed with such symptoms for preservation, and will allow you to “endure” the tone at home. At the same time, she will definitely tell you that now, more than ever, the expectant mother needs peace and relaxation, the absence of any emotional turmoil. Perhaps he will prescribe suppositories with papaverine, No-shpu, Ginipral.

However, if aching, cramping pain in the abdomen is accompanied by the appearance of bleeding, you cannot do without medical help and hospitalization in a hospital. Thus, abdominal pain against the background of bloody discharge indicates an incipient miscarriage; if the reaction is immediate, specialists can save the pregnancy. Therefore, if you suddenly encounter a nagging, nagging pain in the abdomen, the pain does not go away within 2-3 hours, and there is also bleeding, immediately call an ambulance or ask your spouse to immediately take you to the hospital.

Discharge

By the end of the 13th week of pregnancy, discharge from the genital tract may change in nature. During the week, no changes associated with the discharge are observed, but closer to the beginning of the second trimester, the discharge may become thinner and, perhaps, somewhat more abundant. There is no need to worry about this - progesterone, which was dominant up to this point, gave way to estrogen, which caused the liquefaction of secretions.

If the changes concern not only the abundance and density, but also the color, smell, and consistency of the discharge, perhaps the expectant mother should be wary. So, if the discharge acquires an atypical green or yellow tint, mucus or pus, flakes or cheesy lumps appear in the discharge, and to all this is added an unpleasant odor and itching, burning of the genital tract - it’s time to go see a doctor. This picture usually explains the development and progression of a sexually transmitted infection, which should be identified and treated as soon as possible.

Of course, you should immediately go to the doctor if you notice bloody discharge, which, “in conjunction” with abdominal pain, indicates an incipient miscarriage. Timely medical intervention gives a chance to save the pregnancy, but action must be taken immediately to achieve this.

By the way, not always bloody issues from the vagina indicate a threat of premature termination of pregnancy. If spotting and spotting is not accompanied by abdominal pain, but appears more and more after sex with a spouse or examination by a gynecologist, most likely the cause is cervical erosion or some other cervical disease. In addition, spotting can be explained by placenta abruption or placenta previa, which is the result of a fall or blow to the abdominal area, weak vessels bursting under the pressure of the increased blood volume. Be that as it may, the cause of the bleeding must be determined by a specialist, who should be contacted when blood appears.

Ultrasound at 13 weeks of pregnancy

Since the period of the first planned ultrasound covers the period between 10 and 14 weeks, it is possible that the doctor will determine that the optimal option for conducting the study is one of the days of the 13th week.

An ultrasound at the 13th week of pregnancy will clearly show the outline of the baby, tell you about its size, and show how the baby moves, bends and straightens its arms and legs. When conducting an ultrasound examination, the doctor will also be able to assess the condition of the uterus, placenta previa and placenta previa, and determine the approximate date of the upcoming birth.

Ultrasound is also necessary to identify possible fetal malformations. early stages pregnancy or severe congenital anomalies. You just need to remember: the results of an ultrasound examination can in no case be interpreted as a final diagnosis. This is just a reason to conduct an in-depth extended examination and, possibly, consult a geneticist.

Especially for- Elena Kichak

Until the 13th week of pregnancy, the fetus grew in length, and with its onset it begins to gain muscle mass and become rounder. The body grows more rapidly than the head. Bone tissue is actively developing, the skull becomes rigid, and the ribs are already visible.

The 13th week of pregnancy is marked by fetal growth. In size it can be compared to a small peach. Experts believe that it is at this time that it is advisable to conduct prenatal screening, since the fetus is already quite developed. The baby's organs improve, their work becomes more complete, they are able to perform more functions.

The mother's body undergoes hormonal changes. This is a time of sudden changes in mood, the emergence of a desire to eat unusual foods. Particularly important in this period take care of your health. Diet and lifestyle in the 13th week of pregnancy are decisive for ensuring favorable factors for the formation of the baby’s psyche and the absence of any developmental disorders.

Signs, symptoms, sensations

The 13th week of pregnancy is the official end of the first trimester. The risk of miscarriage has become minimal, and if there are no prerequisites or disorders in the body, there is no need to be afraid of it.

If pregnancy occurs in comfortable conditions, the expectant mother has practically nothing to worry about, but the risk of the appearance of small but unusual symptoms that are characteristic exclusively of pregnancy cannot be ruled out. They require the mother’s attention, and when going to the doctor, it is advisable to report them.

Cramps in calves. This phenomenon is usually not dangerous, but if it occurs repeatedly, you should consult a doctor. He will prescribe sedatives for plant based, V severe cases Muscle relaxants will be required.

Dyspnea. It can appear even in completely healthy women; the lack of air is especially severe when carrying out exercise, for example, climbing stairs. The cause of this problem is the growing uterus, which at the 13th week of pregnancy already puts pressure on the diaphragm.

Heartburn. When the symptoms are mild, there is no need to be afraid of this phenomenon. If a woman does not eat heavy or spicy foods in large quantities, this problem is most likely caused by the constantly growing uterus, which puts pressure on surrounding organs, causing them to shift.

Unpleasant sensations, pain in the legs. This phenomenon is especially noticeable after walking or when physical activity. Several factors influence the occurrence of a disorder. The main one is a change in posture, as a result of which a woman’s gait changes due to her growing belly. These features of a pregnant woman’s body are combined with hormonal changes, which can also make themselves felt by a nagging pain syndrome. If fatigue in the legs and throughout the body occurs too often during the 13th week of pregnancy, you should consult your doctor. Rest and lack of overload usually helps.

Hypertonicity of the uterus. If it appears at 13 weeks of pregnancy, this disorder can be dangerous. It can be noticed by the strong and constant voltage lower abdomen, as well as pronounced pulling pain syndrome, which never completely stops. You need to go to the hospital to prescribe medications that are safe for the fetus. Constant rest, sometimes bed rest, is necessary.

Changes or sudden jumps in blood pressure. The uteroplacental circle is fully formed by the 13th week of pregnancy. In this case, blood pressure often decreases, but the changes are not too significant. Weakness, dull or pale skin color are noticeable, and sometimes mild dizziness occurs. Usually selected drug treatment with the help of a doctor, but sometimes it is enough to increase the rest time to heal.

Sometimes blood pressure, on the contrary, increases. This is expressed in increased heart rate, as well as in the appearance of systematic and quite intense headaches. This disorder may be a manifestation of a malfunction of the heart and kidneys, which requires a trip to the hospital and detailed examinations.

Stretch marks. The skin does not have time to regenerate with constant stretching due to the growing belly. Already at the beginning of the second trimester, characteristic lines can form, which brings aesthetic discomfort to the expectant mother. First, red stripes appear, casting a blue color, and then they turn yellow and become gray. To prevent this defect from occurring, it is necessary to carry out a set of measures:

• exercising weight control; the appearance of an excessive amount of subcutaneous fat layer and large folds should not be allowed;
• taking a contrast shower with parallel massage problem areas using a washcloth;
• regular swimming in a pool or other body of water;
• conducting daily physical exercise or yoga classes for pregnant women;
• the use of cosmetics that prevent the appearance of stretch marks or restore normal appearance skin.

Fetal development

The baby turns into a fully formed small person. Parts of the body are clearly visible, the fingers already have a characteristic pattern, and the nails are clearly visible. The shape of the head, torso and limbs does not differ from those that will be characteristic of the fetus at birth. Veins and arteries are clearly visible. The body is covered the thinnest skin. The head is about one-third the size it will be at 9 months.

If there is a girl in the belly, her ovaries have already formed. They function in such a way that at the beginning of the second trimester they have about 3 million formed cells. The weight of the fetus is approximately 28 g. If you measure it from the crown to the tailbone, the total length will be 7 cm.

The gallbladder is already so developed that it secretes bile. The pancreas is active, producing insulin. The formation of the vocal cords is noticeable. All baby teeth are embedded. By the 13th week of pregnancy, they take on the shape in which they will erupt.

According to doctors, during this period there is practically no risk of congenital abnormalities or developmental disorders. The fetus, as in other weeks of pregnancy, can be affected by drugs and alcohol. They can destroy important cells in the baby’s body, so it is necessary to refrain from consuming them. Exposure to large doses of radiation should also not be allowed.

From the 13th week of pregnancy, the general physiological and psychological state of the mother began to influence the psyche of the unborn baby. It is necessary to avoid overexertion and stress, as they can provoke congenital abnormalities in the child’s psyche. You should abstain from junk food, you need to consume healthy, rich in vitamins food, since it is from 13 to 24 weeks that the baby’s vital organs actively develop.

Diet

A baby at 13 weeks of gestation is capable of smelling food. He begins to get used to the mother’s basic diet, so you should only eat foods that are beneficial to the baby not only during pregnancy, but also after birth. You need to eat only the kind of food that a woman is ready to eat after childbirth. If you change the diet, the baby may refuse breast milk.

The fetus is already actively developing, its organs and the skeletal system of the body need to receive large amounts of nutrients. If he receives them in insufficient quantities, then it is impossible to guarantee the successful development of the baby. Also with a lack healthy products maternal health problems may begin, consisting of general weakening or the manifestation of local symptoms such as caries or hair loss. To guarantee good health For yourself and your child, you need to provide a balanced diet.

• buckwheat porridge;
• persimmon;
• spinach;
• pomegranate.

In order for the baby to properly form all the bones and teeth, and to avoid harm to the mother’s body, it is necessary to constantly consume calcium. It is advisable to drink some kind of lactic acid product every day, for example, kefir, fermented baked milk, cottage cheese or yogurt with a small percentage of fat content and without preservatives. Calcium is properly absorbed only when it enters the body along with vitamin D. Moderate exposure to the sun, constant walks in the sun will help. fresh air.

Help proper nutrition is invaluable in correcting pregnancy-related disorders. Constipation may occur at 13 weeks. This deviation is influenced by the constant growth of the uterus and the almost inevitable hormonal imbalance. Many pregnant women notice stool retention; sometimes expectant mothers decide to induce it with the help of medications, since bowel activity constantly brings unpleasant emotions. Doctors do not recommend taking any laxatives, as they can cause a miscarriage.

It is necessary to normalize the frequency and establish the correct diet. You should eat plenty of fiber every day.

Medical recommendations and advice on the lifestyle of the expectant mother at this stage

Ultrasound at 13 weeks of pregnancy Baby at 13 weeks of pregnancy

At 13 weeks of pregnancy, the fetus is already developed. When you look at him, you can see almost the same outline as at birth. In the future, the organs will only grow. During this period, mothers may experience classic pregnancy symptoms, which in most cases are not dangerous if they follow a proper diet, avoid stress and get enough rest.

Video - 13th week of pregnancy

The 13th week of pregnancy is already a third of the way covered by the baby. At this time, the fetus is actively growing, internal organs formed earlier are formed. At this stage, the baby already reaches eight centimeters in length, and its weight is about 25 g. The baby’s nutrition is provided by the placenta, which weighs a little more than the baby - about 30 g.

At the 13th week, the baby's head is a third of the body, so there is no need to worry about the upcoming ultrasound examination. In the future, the body will begin to acquire the correct proportions. The baby is actively moving and moving around in the amniotic fluid, but the mother does not yet feel any movements.

The child’s facial muscles are actively working:

• the baby sucks his finger;
• frowns;
• yawns;
• smiles.

Hand movements are becoming more and more active. The child is able to distinguish the taste and smell of the food that the mother eats, as well as hear everything that happens in environment. The face acquires individual features.

The child’s heart works perfectly and passes through 23 liters of blood per day. The skin is still light in color, through which you can see blood vessels and even internal organs. Blood cells are formed in the spleen and liver, and the pancreas is already producing insulin, storing it in the depot.

At the 13th week, the fetal genitals become more and more visible. IN female body There are already about 2 million eggs, and the boys have a formed prostate. In addition to forming internal organs The skeleton does not lag behind development. Already at this stage, you can notice two clearly protruding ribs, and the development of small bones occurs. The jaw contains 20 baby teeth, the growth of which will begin after birth.

Development of twins

Being pregnant with twins is different for mom. Some women, even at the 13th week, still have signs of toxicosis, and mood changes occur more and more often - hormonal changes are to blame. Typically, at the beginning of the second trimester, such sensations disappear. However, the babies in the belly develop normally and toxicosis only affects the mother.

Babies have formed internal organs that develop and become more complex. Children are slightly smaller than in a singleton pregnancy - about 7-7.2 cm. Don’t worry - it’s quite normal that the babies don’t reach the same height and weight - after birth they will definitely catch up.

An ultrasound examination at this stage may reveal that one fetus is larger than the other. In this case, you shouldn’t worry about a small difference - this always happens, it’s just that one of the babies has better nutrition from the placenta, but the other child also has enough nutrients for development. If the difference in weight is large, the doctor will examine the situation in detail and give his recommendations.

What's happening to mom: sensations

Pregnancy at the 13th week brings long-awaited relief to mothers - toxicosis has already weakened, and the belly is not yet so large as to interfere. Most parameters have returned to normal, but specific sensations still remain.

Changes in the uterus. By the 13th week, the size of the uterus increases significantly; in terms of volume, it already fills its physiological zone and even rises higher. The gynecologist carefully probes the organ to record the height of the uterine fundus. In centimeters, the parameter is equal to the number of weeks of gestation, so at the 13th week the height of the uterine fundus is 13 cm. The width of the organ is about 10 cm.

The organ is easy to palpate, especially in women of asthenic physique. The established parameters are carefully recorded in the pregnant woman’s chart, since with each appointment the doctor must observe an increase in the indicator, which indicates the normal development of pregnancy and fetal growth. The mother’s belly also noticeably enlarges - it becomes rounder and protrudes forward. With well-developed abdominal muscles, the belly is less noticeable.

Urge to urinate. Since the uterus increases in size every day, it puts pressure on bladder and the urge to go to the toilet becomes more frequent. Changes in hormonal levels, an increase in circulating blood volume and the need for fluid also increase the frequency of urination. If urination is not accompanied by pain and stinging, then there is no need to worry - these are just side effects of pregnancy.

Pain in the lower abdomen. The 13th week of pregnancy is often associated with increased uterine tone. Usually this condition does not last long and the woman’s condition returns to normal, but at this time she feels an unpleasant stretching in the lower abdomen, aching soreness. Such unpleasant sensations are also provoked by excessive growth of the uterus, stretching of its tissues and ligaments. Discomfort appears not only in the abdomen, but also on the sides, in the lumbar region. In this case, do not despair - mom needs to lie down and rest, change her body position at work and walk around. If bloody discharge occurs, it is recommended to immediately consult a doctor.

Headache. Under the influence of changes in hormonal levels, a woman’s health becomes unstable, and she is increasingly susceptible to stress and overwork. This can cause headaches, weakness, drowsiness and loss of strength. If your headache is associated with ARVI symptoms, you should consult a doctor.

Discomfort in the back. A pulling sensation in the back is quite normal during the 13th week of pregnancy. At this time, the uterus enlarges, and the body produces the hormone relaxin, which softens the ligaments and tendons. Increased stress on the back invariably causes pain. In this case, the woman should give a small massage without strong pressure on her back to stretch her back muscles. You need to be wary and consult a doctor when there is bleeding, severe cramps in the lower abdomen, elevated temperature body, fever and pain in the kidney area. This condition may signal a miscarriage or pathologies of the urinary tract (pyelonephritis, nephritis, kidney stones, etc.).

Feelings in the chest. At the 13th week, no special changes occur in the mammary glands compared to the previous period. The breasts also feel enlarged, painful and tender to the touch. The mammary glands, under the influence of hormonal levels, continue to prepare for lactation.

Swelling. Water retention in the body occurs under the influence of hormonal changes. The increased load on the kidneys also affects, because a woman needs to increase her water consumption in order to meet the needs of herself and the child.

Hyperhidrosis. Excessive sweating is also associated with imperfect water circulation in the body. The mother's body tries to get rid of water not only through frequent urges to the toilet, but also through sweat glands. Women most often suffer at night, when the amount of sweat increases. Doctors recommend carefully caring for your skin during this period so as not to provoke prickly heat, taking a shower in a timely manner, and also avoiding cosmetics - soap or shower gel; it is better to use herbal infusions.

Vaginal discharge. The 13th week of pregnancy is associated with an increase in normal vaginal discharge. This is the fault of the hormonal background, which affects the production of mucus and the renewal of the vaginal walls. Externally, the discharge has a viscous consistency, mostly transparent, but it can also be white.

There is no unpleasant odor. If the discharge has changed its character, acquired a characteristic sour odor, changed color or contains an admixture of blood, then in this case it is necessary to consult a doctor. If there is discomfort, burning or itching, the doctor will suspect a vaginal infection, do the necessary tests and prescribe safe treatment.

Dyspnea. Shortness of breath does not occur in all pregnant women, but some women large sizes abdomen, if there is a multiple pregnancy, they may suffer from shortness of breath. There is nothing wrong with this if shortness of breath is not accompanied by a feeling of suffocation or chest discomfort. In this case, it makes sense to consult a therapist; you will need to consult a cardiologist.

The first trimester of your pregnancy is ending, anxiety and dangerous periods are behind you. You've probably already registered with antenatal clinic, passed the necessary tests. Toxicosis has become much less pronounced, and, perhaps, has completely disappeared. Hormonal balance is gradually established, you have become calmer and more balanced.

After the end of toxicosis, your appetite has significantly improved, and now is the time to create an optimal nutrition plan so that the baby receives all the necessary substances and you do not gain excess weight.

Your tummy is still invisible, but you already need to remember that tight clothes can squeeze it and interfere with the baby. Therefore, trousers with a narrow belt should be abandoned.

How many months have passed? Week 13 is the first week of the fourth obstetric month of pregnancy, or the last week of the first trimester. You have crossed the barrier, and basically all the baby’s organs are formed. At the 13th week of pregnancy, the baby's weight is about 15-20 grams, and his height is 6.5 - 8 cm.

What's happening?

The size of the uterus has already increased so much that its upper pole can be clearly felt above the pubic bones. If you lie on your back, you can easily feel it in the form of a round formation. The baby is now about the size of a peach. The formation of the placenta continues. Sometimes after long walks you may feel unusually tired and have a feeling of heaviness in your legs. Try to moderate physical activity, but also not to be too passive.

Fetal development at 13 weeks of gestation

Your baby is now developing incredibly actively. Despite the fact that he is still so small, his baby teeth are already forming, his bone skeleton is actively forming, and mommy definitely needs to include additional calcium in her diet.

Pregnancy 12-13 weeks is the period when the baby’s pancreas begins to produce insulin, the most important hormone that regulates glucose metabolism. Other endocrine glands are also formed.

The baby is growing in size every day. His body still looks disproportionate, because his head is much larger than his body. But now the rate of increase in the head does not exceed the growth of the body as much as before. Your baby is already actively moving, despite the fact that you don’t feel any movement yet. Muscle tissue is being formed, and active movements are necessary to strengthen it. While the movements are quite chaotic, however, the baby can easily move in the uterus and swim up to its walls. The periods of sleep and wakefulness alternate quickly, and only during sleep does the baby rest and gain strength.

The development of the gastrointestinal tract progresses: at this stage of pregnancy, villi of the mucous membrane are formed - essential elements digestion. The baby's intestines are completely sterile throughout pregnancy, and only after the first attachment to the breast will he receive beneficial bacteria, which will populate the intestines and promote digestion and absorption of nutrients.

By the beginning of the second trimester of pregnancy, the baby develops facial muscles and a sucking reflex. Already now he can move his lips. The formation of the face continues: the eyes gradually move from the sides of the head to the center, and the ears move from the neck.

The baby's brain is improving. Now there are no convolutions on its surface yet, but the places of their formation are already being laid - small grooves.

At this stage, girls lay eggs. Now there are several million of them, but by birth this number will decrease.

The baby's skin is still very thin, pink, and blood vessels are clearly visible through it. Subcutaneous fat has not yet accumulated. Only in the third trimester will active accumulation of adipose tissue begin.

At 13-14 weeks of pregnancy, sound-reproducing structures are formed, and the vocal cords are almost formed.

Mom's feelings

Expectant mothers at this stage note a significant improvement in their well-being and mood. Firstly, toxicosis of the first trimester has already passed, and if some of its manifestations remain, they no longer cause such discomfort as before. Your appetite has improved, and you can indulge yourself in culinary delights. Try to make them useful.

Usually by this time a screening ultrasound has already been performed, and you know that everything is fine with the baby. And this is the most important thing for every woman. In the early stages, most mothers do not share the peculiarities of their situation with others, but now your condition is becoming more and more noticeable. The belly at the 13th week of pregnancy is still unnoticeable, but a change in gait, sometimes facial features, a change of clothes to looser ones, your high spirits, and a refusal to wear heels becomes clear to many.

You may already notice age spots appearing on your face. Don't worry - after pregnancy they disappear very quickly without leaving a trace. Also typical is the darkening of the strip from the navel to the pubic bones, areolas on the mammary glands, and the genital area. Such changes are associated with changes in the synthesis of pituitary hormones.

You listen more and more to your well-being, your connection with your baby is becoming closer. At this stage, children are already forming emotions, and it is very important that the mother talks more to the baby and strokes the tummy, which is already beginning to become round.

Already at this stage, your mammary glands are preparing to feed the baby, and you may notice how they have enlarged. Now you need to wear comfortable underwear without a frame that does not compress your chest and does not interfere with blood circulation. Special underwear for pregnant and nursing mothers is very convenient.

If your health allows, sign up for sports classes for pregnant women. You need to maintain a sufficient level of physical fitness in order to be in shape for childbirth, recover well, and avoid unpleasant complications. Also try to walk a lot in the fresh air, and if your friends invite you to go outdoors outside the city, don’t refuse!

If you are pregnant with twins

A multiple pregnancy at this stage may still be no different. If you have pumped up abdominal muscles, then your tummy may not yet be noticeable, although very soon it will become rounder. A mother expecting twins must also strictly monitor her diet, get enough rest, and go for walks. Enjoy this easy period of pregnancy, because very soon you will fully feel the double load. Your tummy will grow faster than that of mothers carrying one baby, and the load on your back will be felt. Start wearing a support bandage in time - this will help relieve pain in the back and pressure on the bladder.

Pain and discharge in the 13th week of pregnancy

Most mothers define the end of the first trimester of pregnancy as an easy and pleasant period, not overshadowed by painful sensations. At this stage of pregnancy, any painful sensations should alert the expectant mother.

The uterus is not yet large enough to cause pain due to compression of adjacent organs. Sometimes you may experience a nagging painful sensation in the lower abdomen. Lie down for a while, rest, and if the sensations do not go away, be sure to consult a doctor. At this stage, increased uterine tone occurs quite often.

During pregnancy, a short-term increase in uterine tone is normal. However, constant hypertonicity is dangerous for the baby. If you experience sensations similar to period pain, consult your doctor. You will be prescribed appropriate treatment that will help prolong the pregnancy and prevent miscarriage at 13 weeks of pregnancy.

Proper diet

The manifestations of toxicosis have already noticeably decreased, your appetite has improved, and despite the fact that you want to eat a lot and not always the healthiest thing, you need to control your diet very carefully. First of all, you need to create a diet so that your baby gets everything he needs. nutrients, while preventing you from gaining excess weight. In fact, everything is very simple. You need to remove “unnecessary” foods from the menu as much as possible: those that contain light carbohydrates and at the same time have a minimum of nutritional value. Eliminate or limit as much as possible White bread, replace it with whole grain. Remove pasta from your diet, preferably potatoes. Side dishes that are familiar to many should be replaced with healthier cereals and vegetable dishes.

Your diet should be rich in protein products, because it is the amino acids that make up proteins that are the basis for the construction of all cells of the body. The source of protein is not only meat (and now you should give preference to dietary meat - poultry, rabbit, veal). Protein is found in large quantities in dairy products, especially cottage cheese, in combination with valuable microelements and vitamins.

Constipation is a common problem in pregnant women. They mainly occur in the second trimester, when the uterus puts pressure on the intestines. But it is advisable to start preventing them now. Make it a rule to start your breakfast with a glass of kefir with prunes. Many people neglect this simplest method, but it really significantly improves the condition of the intestines. Your diet should include foods such as dried apricots, bananas, kiwi, and bran. Be sure to eat plenty of fruits and vegetables.

Necessary examinations and inspections

Usually, at this stage of pregnancy, a woman is already registered at the antenatal clinic, and now she needs to visit a doctor once a month. At this time, an ultrasound can be performed. The first screening ultrasound examination should be carried out at 11-13 weeks of pregnancy, the optimal period is 12 weeks. An ultrasound scan at 13 weeks of pregnancy is performed to exclude gross malformations and chromosomal pathologies. At this time there is still an opportunity to conduct genetic research. If severe pathology is detected, pregnancy may be terminated.

The second reason that ultrasound is optimally performed at this particular time is the fact that now, with an ultrasound examination, a specialist will determine the gestational age of the fetus with an accuracy of 2 days. In some difficult situations, it is this age that obstetricians rely on. After all, there are situations when mother cannot name the exact date last menstruation, for example, in the case of certain diseases, or if there was spotting in the early stages of pregnancy.

The study at this stage is carried out with a vaginal sensor. On the monitor you can already see your baby, distinguish where his head, body, arms and legs are, the doctor will show you how his heart beats. But the sex at 13 weeks of pregnancy cannot yet be determined with 100% accuracy. The genitals are still developing. But at the second ultrasound they will tell you exactly who you are expecting - a boy or a girl.

What happens to mother and baby at 13 weeks? This question worries many women during pregnancy. In the article you will find only reliable information, as well as some tips that will help you carry and give birth to a healthy baby.

What important things happen at this stage

The thirteenth week for most women is the period when toxicosis ends. The body gradually adapts to the changes that occur due to fluctuations in hormonal levels. In this regard, the girl’s well-being is improving, which means she can fully enjoy her interesting situation.

The first trimester is over, which means that the threat of involuntary miscarriage has significantly decreased.

How long is 13 weeks?

The thirteenth obstetric period is the 11th embryonic week. Accordingly, the thirteenth embryonic is the 15th obstetric. The end of the 13th week is one month and 7 days.

Despite the fact that this period is marked by some relief of well-being, this does not mean that the expectant mother will not experience any inconvenience.

At the 13th week of pregnancy, a woman will have to face the following changes in her body:

• Digestive disorders (constipation, diarrhea, heartburn, belching). As the uterus grows, pressure occurs on the stomach and intestines, which leads to gastrointestinal upset. In addition, progesterone tends to relax the smooth muscles of internal organs, which affects the peristalsis of the digestive organs.
• A growing belly causes a shift in the center of gravity and a change in gait. This often leads to leg pain and varicose veins. Compression garments and phlebotonics medications help to cope with varicose veins.
• Another unpleasant phenomenon is increased uterine tone. This condition is expressed in nagging pain in the lower abdomen, as if it turns to stone. Doctors usually prescribe rest and bed rest for such patients. In especially severe cases, drug treatment is necessary.
• Nagging pain in the lower abdomen and lower back. Many pregnant women experience this symptom at 13 weeks. Discomfort is associated with the growing uterus and the effect of the hormone progesterone on the vertebrae. If the discomfort goes away at rest, there is no need to worry. You should immediately consult a doctor in a situation where the pain is severe and accompanied by bleeding.
• During the period of gestation, the mother's immune defense decreases. This is necessary to preserve the fetus. Against this background, nasal congestion and weakness may occur. Another common occurrence is thrush. In this case, white cheesy discharge with an unpleasant odor and itching in the genital area are observed. Treatment of a fungal disease should be carried out under the supervision of a physician.

In addition to all the delights, at the 13th week of pregnancy, many mothers experience a decrease or, conversely, an increase in blood pressure. In this case, the girl experiences symptoms such as weakness, dizziness, headache, and sometimes fainting. This condition requires constant medical control and the use of antihypertensive or hypertensive drugs.

Many drugs are prohibited during pregnancy. In this regard, self-medication is not allowed. Medicines must be prescribed by a specialist.

What happens to the body: external changes

Thirteen weeks is the beginning of the second trimester. It is unlikely that a woman will be able to ignore external changes. First of all, this concerns a rounded tummy. Every day the fetus grows, and accordingly, the size of the uterus increases. The lower abdomen becomes denser, the woman feels a hard lump. At this stage, you should take care of a comfortable wardrobe. Trousers and jeans should not squeeze the stomach. In addition, you need to give up shoes high heels, tight shoes. This is especially true for women suffering from edema and varicose veins veins

At the 13th week of pregnancy, the mammary glands noticeably enlarge. Women no longer fit into their old bras. Now doctors recommend wearing comfortable underwear made from natural fabrics. You can use special bras for pregnant women.

The expectant mother notices itching on the chest and tummy area, and stretch marks often appear. They are especially pronounced if there is rapid weight gain. A light massage, a contrast shower and the use of special moisturizing creams will help prevent such changes in the skin.

The size of the abdomen at 13 weeks depends on the constitution of the pregnant woman’s body and some other features. Often a dark pigment line appears from the navel to the pubis. In girls who are predisposed to pigmentation, spots may appear on other parts of the body. No need to worry about this. Almost immediately after childbirth, these signs will disappear on their own.

This is what bellies look like at 13 weeks pregnant

In obese mothers, the tummy may look larger at this stage, which is due to the presence of a fat layer.

The weight of your baby is now approximately 15-20 g, and the height is 7-9 cm. The size of a child can be compared to a nectarine. On an ultrasound, you can see a little man who no longer resembles an embryo at all. The head becomes more proportional to the body, the baby actively moves his arms and legs, bends and unbends his fingers, and breathes amniotic fluid.

Other changes:

• Bile is produced by the gallbladder;
• the pancreas synthesizes insulin, which is necessary for normal glucose metabolism in the body;
• during the waking period, the child constantly performs chaotic movements, training the muscular system;
• the eyes, previously located on the sides of the head, gradually move closer to the bridge of the nose;
• The formation of facial muscles continues, the formation of baby teeth ends;
• the sucking reflex develops.

At week 13, the heart works quickly and is capable of pumping 20 liters of blood per day. Heart rate is now 140-170 beats per minute.

The brain is actively developing, the rudiments of the first convolutions appear.

Dangers at 13 weeks of pregnancy

A young mother should be attentive to her health throughout her entire pregnancy. Now her body is very vulnerable, and she is responsible not only for herself, but also for the tiny life developing under her heart. Let's consider what complications may arise during this period.

Cold

During the period of bearing a child, even a common cold can provoke many undesirable consequences. Particularly dangerous are diseases such as chickenpox and others. Sometimes, when the body is damaged by an infection, miscarriages occur or serious pathologies develop, due to which the doctor may even recommend terminating the pregnancy.

Treatment of acute respiratory viral infections, acute respiratory infections, influenza and other diseases is complicated by the fact that not all traditional medications are allowed for a pregnant woman. If you rise heat, doctors prescribe paracetamol-based antipyretics, bed rest and plenty of fluids.

It is known that any disease is easier to prevent than to treat. The following recommendations will help a young mother not get sick:

• dress according to the weather, during periods of epidemic try not to visit crowded places;
• saturate your diet with fresh vegetables and fruits, take vitamins;
• When the first signs of a cold appear, you can resort to traditional methods treatment (tea with lemon, bed rest, drinking plenty of fluids);
• if you have a high temperature, it is better to call an ambulance. A specialist will help you choose medications that are safe during pregnancy.

It should not be overlooked that at week 13 the temperature may be subfebrile. Basal temperature remains within 37 degrees. There is no need to bring down this temperature, because it is a completely normal phenomenon against the background of increased progesterone production.

Painful sensations

Painful sensations of a moderate nature are a completely natural phenomenon during the period of bearing a baby, which should not bring concern to a woman. They mainly occur due to increased tone of the uterus. If the pain is quite severe and is accompanied by other signs, there is no need to endure it. In such a situation, it is better to consult a doctor.

Pain may also occur in the following ways:

• in the area of ​​the lower extremities, which indicates a deficiency of certain microelements in the body, in particular calcium;
• headaches appear with increased or decreased blood pressure;
• discomfort in the lower back may occur due to an enlarged abdomen;
• due to digestive disorders, minor pain in the stomach or intestines may also develop.

At 13 weeks, a woman should learn to distinguish acceptable physiological pain from pathological pain.

Pathological pain is usually intense and does not go away on its own. It may be accompanied by symptoms such as vomiting, nausea, headache, fever and others. In this condition, you should consult a doctor immediately.

Discharge

Women who closely monitor their health know that normally, discharge should not have an unpleasant odor, its consistency is mucous, and its color is transparent. Deviations from the norm almost always indicate the presence of one or another pathology:

• Brown - indicate the presence of a small amount of blood in the secretion, which is not the norm. They can appear after sex or a gynecological examination, but often this symptom also indicates more dangerous conditions, for example, fading pregnancy or an incipient miscarriage.
• Yellow or grayish - may indicate infection of the genitals. In addition to a yellowish secretion with an unpleasant odor, a woman may experience itching and burning. If these signs appear, you should undergo a gynecological examination.
• Light pink or beige - often appear in the presence of cervical erosion. If they are abundant, you must inform your doctor about this.
• Watery - appear when amniotic fluid leaks. If this type of discharge is detected, it is important to consult a gynecologist. Leakage of water often occurs in such a dangerous condition as depressurization of the placenta.

Be that as it may, if any pathological secretion appears from the vagina, you should not delay visiting a doctor. Excessive caution at 13 weeks of pregnancy will not harm.

The most dangerous sign during pregnancy is bleeding from the vagina. If you experience bleeding, lower abdominal pain, nausea, dizziness, pain or other alarming symptoms, you should immediately call an ambulance.

The following conditions can cause bleeding at week 13:

• placenta previa or abruption;
• the presence of a hematoma on the placenta;
• low placentation;
• cervical injuries during a gynecological examination or during sex;
• poor elasticity of blood vessels that burst as the uterus grows.

To clarify the cause of bleeding, mommy needs to undergo an ultrasound and other examination methods. If there is a threat of miscarriage, the woman is advised to be kept safe in a hospital setting.

Doctors judge the healthy development of a child by measuring its parameters during an ultrasound examination. What do they look for on an ultrasound:

• coccygeal-parietal size (CTP) – up to approximately 65 mm;
• biparietal size (BPR) – from 18 to 25 mm;
• length of the nasal bone – from 2 to 4.3 mm;
• fetal head circumference – approximately 70 to 95 mm;
• thickness of the collar space (TVP) – no more than 3 mm;
• roundness of the fetal abdomen – from 60 to 80 mm;
• femur – from 7 to 11.5 mm.

A baby's heart rate in the thirteenth week of pregnancy should be between 140 and 170 beats per minute.

In the photo you can see what the baby looks like at 12-13 weeks after conception.

Here you can see a twin pregnancy

At this stage, with the help of an ultrasound examination, it is already possible to understand who is in the tummy, a boy or a girl. If a woman has gone through IVF (artificial insemination), pregnancy with twins or triplets is common.

It is not always possible to accurately determine the sex of a child. To do this, you can use 3D ultrasound or wait a while.

What tests are performed at this time?

In addition to ultrasound, the first screening includes some other studies. This includes a general blood and urine test, blood biochemistry, testing for TORCH infections, and testing for Rh conflict between parents. Testing for possible chromosomal abnormalities in the fetus is mandatory. These include:

• Study of progesterone levels. This test helps assess the child's development different dates, exclude a frozen pregnancy, identify delayed fetal development, prevent miscarriage, and so on.
• HCG analysis. Human chorionic gonadotropin is the so-called pregnancy hormone. By its amount in the blood it is possible to monitor whether the child is developing normally. HCG begins to increase tens of hundreds of times from the first days of conception, and after 11-12 weeks it begins to gradually decrease. Read more about this hormone.
• Test for estradiol. It shows whether there is a threat of miscarriage and what condition the placenta is in.
• Alpha-fetoprotein protein (PAPP-A). Another analysis that helps identify some chromosomal pathologies (Down syndrome, Edwards syndrome and some others).

If a woman is over 35, has a history of miscarriages and frozen pregnancies, the family already has children with genetic abnormalities or a marriage between blood relatives, tests for chromosomal abnormalities are mandatory.

All data is decrypted exclusively by a specialist. You should not try to establish a diagnosis on your own by getting tests in hand.

Can a fetus freeze at 13 weeks and why does this happen?

The development of a child's life may stop at 13 weeks of pregnancy. This is due to many factors, including:

• disruption of hormone production;
• chromosomal abnormalities in the fetus;
• transfer by mother infectious diseases;
• abdominal injuries;
• strong emotional stress;
• abuse of bad habits;

The height of the uterus is measured by the doctor at each routine examination. Normally, the height of the uterus is equal to the number of weeks of pregnancy. Therefore, at week 13 she will have a height of 13 cm.
