Breast changes and early signs of pregnancy
Even before a positive pregnancy test, many women report breast changes as the first indication that they might be pregnant. Because breast changes are also common before or during a period, it can be hard to distinguish between the two, particularly for someone who’s trying to get pregnant or who really doesn’t want to be pregnant.
Breast changes in early pregnancy are the result of an increase in progesterone levels, as well as the initial stages of milk duct growth. Breast sensations may change, as tingling and soreness, usually around the nipples, increases. The breasts may also get larger, while both the nipples and areola become larger and darker.
