Breast Changes in Early Pregnancy

Some of the most dramatic changes in early pregnancy are the changes that occur to the breasts. Many women go up a bra size or two overnight—a situation that can be either disconcerting or delightful, depending on how you feel about your breasts.

The hormones at work behind this sudden increase in breast size are also responsible for other changes in the appearance of your breasts. Your nipples sometimes become enlarged and erect, the areola broadens and becomes darker, and the increased blood flow through your body causes the veins in your breasts to become more visible.

Many women also experience a certain amount of breast discomfort during this stage of pregnancy. The swelling, tingling, throbbing and aching that you may be feeling are indications that your body is getting ready to go into the milk-production business a few months down the road.
