13 weeks pregnant: how is your baby developing?

A fetus in the 13th week of pregnancy is about 80 mm and weighs about 15-20 g, so it is the size of a tangerine. Although it is already quite large and shaped, has all the organs, it is still completely dependent on the mother's organism.

It is from him, through the placenta, that he receives oxygen and nutrients without which he would not survive.

The placenta begins to function around the 13th week of pregnancy, when it reaches full maturity and takes over the role of placental villi. It is connected by blood vessels to the uterine wall.

Your child can already do a lot: he can move, although you do not feel it yet, he waves his fingers and limbs, he moves his head. Without movement, it can only last a dozen or so minutes. These exercises strengthen his muscles.

  • The intestines continue to move deeper into the abdominal cavity, the liver begins to produce bile and the pancreas produces insulin,
  • the child's face changes - the eyes move to the nose, and the ears - to the sides of the head, that is where they will be finally located. Although the ears are already developed, the sense of hearing does not work yet, but the little one reacts to sounds. Probably the fetus perceives them as vibrations with its skin,
  • develops a newborn reflex to look for a breast. When his mouth accidentally touches the uterine wall, he turns his head over, like a newborn baby is looking for a source of food.

This is because the production of the hCG hormone, which is responsible for nausea, is decreasing - it is no longer needed by the baby, because it does not have to stimulate the yellow body to produce progesterone.

Now it is produced by the placenta, and progesterone is responsible for the slower bowel movements, which lead to problems with defecation, heartburn and gas.

To avoid them and help your digestive system work, drink plenty of water, eat less but more often, and eat high-fiber foods.

In the 13th week of pregnancy, you may also notice further changes resulting from pregnancy: some mothers complain of deterioration of their skin, or - on the contrary - improvement of its condition.
