Pregnancy Calendar

The pregnancy calendar is necessary for a pregnant woman to have a clear idea of what changes occur in the process of intrauterine development of her unborn child.

It is made up for weeks and trimesters, and every new pregnancy week makes adjustments to the development of the fetus. The first 13 weeks of pregnancy are the most dangerous, since any adverse effects on the fetus can lead to congenital pathologies or loss of pregnancy. In the second trimester the fetus continues to grow rapidly, and by the 20th week most women begin to feel its movement.
