Oestrogen and Progesterone — deserves most of the blame for changes and tenderness. Other factors include the (good and necessary) fat that’s building up in your breasts and increased blood flow to the area. The bottom-line is that your breasts are getting ready to become milking machines in just a few short months.
What You Need to Know
In addition to that tender feeling, you’ll likely notice a few changes in your breasts during pregnancy:
* Your nipples. In addition to the aches and tingling, your nipples may be protruding more than usual and most likely to be very tender at this time.
* Your areolas. If you’re like most women, your areola (the dark area around the nipple) has become darker, possibly spotted, and just plain bigger – a phenomenon that will continue as the months pass. Your areola will also be showing little goose bumps (actually sweat glands) that supply lubrication to the area.
* Your veins. You’ll also notice a complex highway of veins ( for light skinned women) just below the skin’s surface, which carry nutrients and fluids from mother to baby.
The good news: Your breasts may continue to grow, but they’ll probably stop hurting after the first trimester. Even better news: Your breasts will almost return to their original shape and size in the months after birth.
