Breast Sore during Pregnancy

Hormonal changes during pregnancy cause increased blood flow and changes in the breast tissue, which may make your breasts feel swollen, sore, tingly, and unusually sensitive to touch. Some women describe the sensation as an exaggerated version of how their breasts feel before their period.

Breast tenderness is one of the earliest signs of pregnancy. It usually starts around 4 to 6 weeks and lasts through the first trimester

Causes of sore nipples and breasts before menopause

There are 2 main reasons for sore nipples/breasts before menopause:

• Post-ovulation - During your menstrual cycle the 2 main hormones at work are:
  • estrogen before ovulation and
  • progesterone which starts to act around the time of ovulation

  Progesterone causes water to be retained in the body. The main reason for this is to prepare the uterus for a possible pregnancy by making the uterus rich in water and food for the anticipated pregnancy. Unfortunately, this same effect is felt throughout the body. Storing of water in the breast tissue causes it to become stretched leading to painful breasts and sore nipples.

How to reduce the soreness?

Your best bet is to find a few good, supportive bras. Take the time to get fitted by a knowledgeable salesperson in a large department store or maternity shop.

You may find that bras with underwires are less comfortable now. To prevent chafing, look for soft material with no seams near the nipple. Cotton bras will be more comfortable and breathable than synthetic.
