Breast Changes In Pregnancy: What To Expect


Breast changes during pregnancy have to be some of the most dramatic. Many women don’t realize that this is possible, which is why it’s so important to educate oneself about what’s happening with your breasts while you’re pregnant.

Breast tissue expands during pregnancy to support the growing fetus and its growing mother.

Like many changes during pregnancy, these breast changes aren’t always normal. For example, you may notice your breast look bigger, feel softer, or bleed more easily during pregnancy. But there are also different types of breast changes that are totally normal and can be treated.

Along with expanding, the skin of your breasts becomes thinner and changes color, Dr. Anne Hughes, M.D., medical director of the Breast Center at Weill Cornell Medicine in New York City, tells SELF. If you notice the skin of your breasts becomes pale or grayish, that’s a sign that you’re pregnant and hormone changes are to be blamed.
