Swollen mammary glands and swollen veins on the chest are signs of early pregnancy, manifested mainly in the later stages. When pressing on the nipples, yellowish colostrum is released. And in the first months of pregnancy, a woman may feel only some discomfort in the chest area. Also noticeable signs of early pregnancy are Montgomery tubercles. These are small outgrowths that form in a circle around the nipple immediately after successful conception. Outwardly, they look like warts filled with sebaceous matter, but in no way disrupt the functioning of the mammary glands, do not affect the health of the mother.
