A woman's breasts increase in size and fullness during pregnancy. As the due date approaches, hormone changes will cause your breasts to get even bigger to prepare for breastfeeding. Your breasts may feel full, heavy, or tender.

In the third trimester, some pregnant women begin to leak colostrum (coh-LOSS-truhm) from their breasts. Colostrum is the first milk that your breasts produce for the baby. It is a thick, yellowish fluid containing antibodies that protect newborns from infection.

What Might Help:

• Wear a maternity bra with good support.
• Put pads in bra to absorb leakage.
