Breast growth is due to the increase in the hormone progesterone during pregnancy. From the third month of gestation, the breasts become larger and heavier, and estrogens promote the development of the ducts for breast milk.
The nipple-areola may become somewhat darker and, especially in the last months of gestation, marked blue veins may appear due to the increased blood flow in this area.
It is advisable to take special care of the breasts throughout the pregnancy, as they will be very important for the baby's nourishment in the first months of life. It is advisable to wear comfortable underwear, without seams or underwire, and preferably made of cotton. To prevent stretch marks from appearing, apply the cream daily.
