12 gestational week

12 gestational week corresponds to the 3rd month of pregnancy and falls in the first trimester. For some doctors, this gestational week is defined as the child’s first birthday. You are already 1/3 of the way through. The anxious and risky trimester will be behind you. The risk of miscarriage is significantly reduced. You can now share the happy news to all your relatives and friends and also to your employer.

Size and development of the embryo in the 12th gestational week

  • Height – 5.4 cm.
  • Weight – 14 g.
  • Head circumference – 7.0 cm.
  • Abdominal circumference – 6.3 cm.

The future child continues to grow and already weighs almost 14 grams. In the past week it has grown by more than 1 cm and has reached a height of 5.4 cm and a weight of 14 g. The brain continues to develop extremely rapidly. Blood vessels are forming in it, which will later be saturated with blood.

Now at every touch to the uterine walls the fetus reacts more consciously. The movement of the chest can be noticed. The heart beats more frequently – more than 150 beats per minute. With special instruments, the heartbeat can be heard.

In the 12th gestational week, the formation of the base of the milk teeth and vocal cords begins. The diaphragm is formed, which separates the breast from the peritoneum. Under the influence of testosterone in boys, the sexual organs continue to form.

At the end of the third month, the uterus is already 15.7 cm thick. The fetus receives nutrients through the placenta, which is connected to it through the circulatory system.

The slightest changes in the mother’s condition are capable of provoking a reaction in the fetus. The formation of the placental system provokes a decrease in the load on the woman’s organism.

What does a pregnant woman feel during the twelfth gestational week?

Over the past three months, the woman’s organism has been adjusting to pregnancy. The unpleasant sensations characteristic of this initial period are now a thing of the past.

It is advisable for her to continue to take care of herself. Full sleep, active physical movement and calmness are mandatory.

And during this week, the risk of venous networks due to the tension that the uterus exerts on the blood vessels is high. You can lower the strain on the legs by occasionally lifting them aloft. Sleep with your feet positioned slightly higher than your body.

Some pregnant women prefer to wear special socks and stockings. You can buy them in almost any pharmacy.

To strengthen the walls of the blood vessels, we recommend taking vitamin C.

Keep in mind that at this stage the peristalsis of the intestine decreases its activity. The risk of constipation is increased.

A pregnant woman may feel that her heartbeat is accelerated. It is due to increased blood circulation.

In the twelfth week, the load on the heart, lungs and kidneys increases, therefore it is not advisable for a pregnant woman to overwork, overeat and make big changes in her lifestyle.

Ideally, vaginal currents should continue to be milky-transparent and moderate. Their smell should be slightly acidic. Since the immune system is still weakened, you may feel fatigue. It is not impossible to develop candidiasis. It provokes itching in the vagina and copious discharge. Since it is capable of masking other infections, it is advisable to see a doctor.

The menu of a pregnant woman in the 12th gestational week

At this stage of pregnancy, the body’s need for vitamins increases. Therefore, it is advisable to take special complexes of vitamins and minerals for pregnant women. Among them, the most important are vitamins of group B: thiamine, riboflavin, pyridoxine, cyanocobalamin. They are actively involved in the work of the nervous system, metabolic processes and the production of estrogens.

For the formation of bones, it is necessary to take vitamins D and E. Enrich the menu with foods that contain them. It is imperative to consult a doctor to specify the daily norm.

What is seen on ultrasound?

In the 12th gestational week, the fetus is already moving easily in the uterus. The amniotic fluid is constantly renewed. The functions of the corpus luteum have long been taken over by the placenta.

The nose, mouth, eyes and eyelids are prominent. The future child can purse its lips and demonstrate a sucking reflex. On ultrasound examination, the formation of some parts of the brain can be traced. The heart beats at a rate of 110-160 beats per minute.
