Thirteenth week of pregnancy

Future child.

Height – 8-10 cm, weight – 25-30 gr.

This week begins the active growth of the child, lasting up to 24 weeks. The head, which previously increased faster than the rest of the body, gradually begins to reduce growth rates. By the end of 21 weeks, it will be only a third of the total length of the child, while now it is about half.

At the time of birth, the child’s body will be 4/5 of its total size, and the head – only 1/5. The adult proportion is 7/8 to 1/8 respectively.

The placenta takes care of all the functions of feeding the baby and supplying it with oxygen, as well as the production of hormones of progesterone and estrogen. Therefore, in pregnancy usually ends toxicosis. The weight of the placenta is about 30 grams this week.

The placenta passes the baby oxygen, which is inhaled by the mother, nutrients from her food, as well as protective substances from the immune system. In appearance, the placenta resembles a pancake saturated with blood vessels, from which the umbilical cord departs.

Through the umbilical cord, the mother’s blood passes to the child, and in the opposite direction, unnecessary toddler waste of life, which rejects the amniotic fluid.

The eyes of the child are not yet open – the eyelids cover them completely. But the kid grows teeth. Yes, yes, at this age, all 20 milk teeth are laid, although at birth they will not be visible. In addition, the mouth completes the formation of taste buds.

In the intestine, there are special villi that help digest food. The pancreas is also trying – it is already producing insulin.

The muscles gradually build up, the child rotates his head more actively, moves the handles. The baby “invents” one more reflex – sucking. Now, if he already has long enough handles, he can suck his thumb.

This week his genitals are finally formed. At the boy the genital tubercle lengthens and forms a penis, and at the girl – a clitoris. The sex of the child can already be clearly distinguished by ultrasound.

Future Mom.

If you have not done a double test and an ultrasound examination of the collar zone (see 11 weeks), then you have 6 more days left, when it can be done, later the test data will become inaccurate.

Morning sickness in most women is a thing of the past. The most golden time of pregnancy begins – the second trimester. Indeed, there is no toxicosis any more, fears of miscarriage and genetic abnormalities are almost released, the tummy starts to grow, but still does not reach such large sizes as in the last months, and the woman, at last, feels really pregnant.

Now you can afford to relax a bit before the 16th week, when the next stage of testing is to be done, and evaluate the changes that are happening with you.

So, the waist is already fat, as you might have noticed earlier. The change in the circumference of the waist is affected not only by fat deposits, but mainly by the increase in the uterus. Therefore, many women even lose weight, judging by the weights, but despite this, the waist of them continues to grow steadily.

The uterus has now grown to 10 cm in width and 13 cm in height and emerged into the abdominal cavity. It becomes more and more soft, it is easy to stretch, so the child is comfortable and comfortable in it. You can control the condition of your uterus yourself, gently touching it every day with your hands (it is located behind the front abdominal wall).

If you feel that the uterus is tight and tense, then you have an increased tone. It is worth to lie down in bed, relax and relax, if possible. If you experience discomfort and pain, call your doctor. Just in case, have No-shp or Magne6 at hand, but still consult a doctor before taking them.

The breasts are full and your favorite bras do not suit you any more. Prepare for the fact that by the end of pregnancy each breast will weigh from 400 to 800 g (if before pregnancy your breasts were of the sizes A and B).

It changes not only the fullness, but also the shape of the breast.That’s why women are advised to wear bras for pregnant women, designed specifically for expectant mothers. They are more expensive than usual, but they are very convenient. They also contribute to the prevention of stretch marks and venous nets, often occurring during pregnancy.

Many women darken strongly the areola around the nipple to brown and even reddish-brown, and so-called “Montgomery hillocks” appear. Thus, the breast prepares for the future feeding.

In the second trimester (who used to have someone later), the breast begins to give off colostrum, especially when it experiences an additional effect (massage, nipple irritation, sexual arousal, etc.).

Unpleasant surprise will be the appearance of stretch marks (striae). These are red stripes on the abdomen, hips, chest. Some women are lucky, and they do not have stretch marks. Fight this phenomenon is useless, even if you promise in advertising the wonderful effect of lotion or cream.

However, cosmetics are always at least something useful for the skin. If you do not get rid of the stretch marks, but the skin will have a healthy appearance, it will become smooth and soft. So decide for yourself what to buy and for what money.

We remind you that it is harmful.

– it is harmful to overwork (including at work). It’s time to talk with the employer about the fact that you are pregnant (for details and legal details of this conversation, see the article on the 14th week of pregnancy).

– It is harmful to wear tight clothes, especially squeezing your waist. When in olden times ladies were fond of tight corsets, children often appeared with congenital anomalies of bones of the skeleton and head, or the mother provoked miscarriage. Now, of course, we do not wear corsets, but the squeezing in the waist area of ​​the pregnant tummy is not useful, and terribly tedious.

– it is harmful to eat caffeinated foods. Scientists claim that 4 cups of coffee a day lead to the birth of a child with a reduced weight and a small head or with a propensity for asthma. Many believe that there is a connection between coffee and miscarriages. Try to limit yourself, even if you are a “coffee-chocolate addict”. At least cook yourself a coffee weaker.

– it is harmful to conduct X-ray examination, tomography and magnetic resonance imaging (MRI). Only exceptional cases associated with a serious illness of the mother, it is permissible to deviate from the rules and expose the baby to harmful radiation and vibrations.
