What happens to a woman at 12 weeks of pregnancy?
The future mother at this time usually feels very good. Toxicosis at 12 weeks gestation, as a rule, no longer annoys; the belly is practically not performing, and therefore does not prevent a woman from leading a normal life, and even sleeping on it.

Since the uterus at the 12th week of pregnancy already rises above the pubic bone, this most important female organ is as wide as 10 cm wide.

The breast of the future mother begins to increase. Sometimes itchy and some raspiranie in this area can disturb. Doctors recommend it is from this time to start wearing a special bra, well supporting the breast. On the abdomen, a dark brown band may appear, extending from the navel downwards, which will disappear after delivery. On the neck and face can appear, the so-called "mask of pregnant women" - brown spots of different sizes, which also disappear after childbirth.

The skeleton becomes stronger, bone substance is formed in it. On the body appear separate hairs. In the intestine, peristaltic contractions occur periodically, and bile begins to be produced in the liver. The thyroid gland is already fully formed; it begins to be included in the regulation of metabolism, as well as in the development of the central nervous system.
With a gestation period of 12 weeks, the sex of the child is likely to be determined by a planned ultrasound examination conducted at approximately 12-13 weeks as part of the first trimester screening.

He also knows how to open and close the mouth, frown and smile. At the end of the first trimester, the baby begins to excrete urine. His face is very much like the face of a newborn. Eyes can now open and close, on the tiny fingers appear nails.
