Future child

Height - from 1 to 1.5 cm, weight - about 0.8 g.

Your baby finally develops embryoplacental blood circulation and hemochorial type of nutrition of the embryo. This means that the chorion (the shell of the embryo) is in direct contact with the mother's blood. The placenta thickens, the umbilical cord is attached to the wall of the uterus. The umbilical cord is clearly marked.

The heart rate reaches 140-150 beats per minute, almost twice that of the mother. Interestingly, the embryo already has its own blood type.

The baby's central nervous system is almost complete. The main thing this week is the start of intensive skeletal formation. The body of the embryo is divided into arms and legs. The foot is separated from the anlage of the leg. Gradually, the fingers are separated from one another. Next week the hands and feet will be well formed. The arms are lengthened, the elbow joint appears.

The head of the unborn child is disproportionately large compared to the rest of the body. She is leaning forward. On the face, you can distinguish an eye on which eyelids are already beginning to form, there is a lens, a pupil, a cornea and an iris. The tip of the curious nose stands out and the ears gradually detach. The rudiments of future teeth begin to form in the mouth.

Muscles are gradually developing, the unborn child can even move, but the mother still does not feel his movements. The digestive tract begins to form: the esophagus, the anterior abdominal wall, the small intestine, the rectum is already present. The sternum develops.

The respiratory system also develops in the embryo: the trachea is pulled downward, forming horns - these are the rudiments of future bronchi.

A tiny tubercle appears between the legs - the external genital organs will then develop from it. But it is still impossible to determine whether it is a boy or a girl, although the future child already definitely has its own gender from the moment of conception.

This week, the baby usually disappears gill slits and the right umbilical vein (only one left one remains). But the tail of the child lengthens and bends even more - it will finally disappear only after a couple of weeks.

Future mom

So, you made sure that your period never came. If you have not done the test yet, it's time to do it, and at the same time make an appointment with the doctor at the antenatal clinic.

In the meantime, a mucous plug is created in the uterus of the expectant mother, separating the unborn child from the outside world. This plug will remain in your body until the very birth and will be released no earlier than a few days before them (usually a few hours). It is a fairly voluminous lump of mucus mixed with blood.

Due to the change in hormonal levels, your skin on your face may deteriorate, acne, spots or excessive dryness may appear. It is imperative to keep the skin clean, perhaps use powder and foundation in moderation, and also buy special healing lotions and soaps.

The biggest danger of this period is the possibility of miscarriage. The main signs of a miscarriage are similar to those of an ectopic pregnancy (see week 4):
1) bleeding with bright red or brown blood.
2) sharp cramping or pulling pains in the abdomen, similar to pain during menstruation, as well as back pain.

Discharge of some blood from the vagina during early pregnancy is common. Do not worry if you see only a drop or slight daub, if it is not accompanied by pain in the uterus. However, even in this case, it is worth giving your body an emergency respite and lying down with your legs up.

But if there are two signs at once or only pain, without bloody discharge, you should call the doctor and go to bed. If you have already had cases of termination of pregnancy, missed pregnancy or medical abortion, you should call your doctor immediately.

Why does an early miscarriage occur? Scientists believe that this phenomenon is quite frequent, just not every woman with a delay in her period immediately makes a pregnancy test. By the time of the miscarriage, she simply does not know that she is pregnant, and considers the bleeding to be another menstruation.

Sometimes the delay doesn’t even have time to come, and your period may be essentially an unnoticed miscarriage. According to scientists, about 10% of confirmed pregnancies end in miscarriage, scientists are ready to expand this threshold to 20%.

In most cases, a woman is not able to prevent a miscarriage, since the rejection of the ovum occurs due to serious defects in the chromosomes of the embryo, hormonal deficiency, infections previously transferred by the mother, and the unfavorable environmental situation in the region.

But you should avoid actions that can provoke a miscarriage, namely:
- No need to lift weights and children.
- No need to do those household chores that are associated with significant physical stress, for example, washing floors by hand, hanging curtains, general cleaning, repairs.
- Try to do everything so as not to fall or in any other way not damage your body.
- Get rid of stress and stress-provoking situations.
- Do not take excessively hot baths, avoid new unfamiliar drugs and exotic foods.
- You should be careful with sex, especially if you have had miscarriages in the past.

Sometimes it is even better to abstain from sex for a while, since during orgasm a woman's uterus contracts greatly, which can provoke a miscarriage.
But in the vast majority of cases, sexual relations do not harm pregnancy, and doctors recommend abstaining only before childbirth.

If you do have a miscarriage, your doctor usually prescribes curettage after examination. But remember that in order to confirm the diagnosis, it is necessary to first carry out tests and do an ultrasound examination, since bleeding may not be associated with fetal development problems. In addition, if the fetus is still alive, there are drugs that will help it gain a foothold in the uterus and continue its development.

Other problems of pregnant women during this period are toxicosis and heartburn. You can read about how to cope with toxicosis in the recommendations for 6 weeks of pregnancy. Now we will talk about the second scourge of expectant mothers - about heartburn.

If toxicosis usually disappears from the 12th week of pregnancy, then heartburn only intensifies towards a later date. The emergence of unpleasant annoying sensations in the esophagus is due to all the same hormones of pregnant women - progesterone and estrogen.

These hormones help relax the smooth muscles of the esophagus. As a result, food travels more slowly, remains in the esophagus, and causes distress. Heartburn occurs when the muscle that separates the esophagus from the stomach contracts and hot stomach juices and food debris enter the esophagus. All this irritates the mucous membrane, causing discomfort. In the later stages, the problem worsens, since the enlarged uterus begins to press on the stomach additionally.


1. Do not eat a lot, do not overload the stomach.
2. Do not wear tight things that tighten your belly and waist.
3. Eat slowly and chew well.
4. Exclude from the menu spicy, hot or fatty foods, canned food and meat products such as sausage, bacon, hot dogs, as well as chocolate, coffee. Drink milk more often, but in small doses.
5. Don't smoke.
6. Do not bend over sharply, squat better.
7. Sleep on a high pillow with your head raised about 20 cm.
8. Take special drugs such as Maalox, Gaviscon and others. Please note: they must be marked that the drug is suitable for the treatment of heartburn in pregnant women.
9. In an emergency, a teaspoon of baking soda can help, which must be swallowed and washed down with water. The procedure is not pleasant, so many people first dissolve soda in a glass of water, but for some reason the second option usually works worse.
