Breast tenderness during pregnancy is a very common thing. In fact, it is often one of the very first signs that you are pregnant. Breast tenderness simply refers to the soreness, swelling, and sensitivity that you feel in your breasts during pregnancy. Typically, this tenderness begins between the fourth and sixth week of pregnancy, and continues through the first trimester. Most women will find that their breast tenderness disappears in the second and third trimesters, although you may notice that your breasts do feel sore from time to time throughout your pregnancy.



Some women have breast discomfort or pain right before their period, while for others, this starts during ovulation and continues until their period begins. It is common, however, for a woman's breasts to feel "bruised" or extremely sensitive right before menstruation. Often times, breast discomfort is caused by fluctuations in hormone levels throughout the menstrual cycle (regardless if women are on the pill or not). Sometimes birth control pills are prescribed to help alleviate this achiness or tenderness. In addition, that bruised feeling can be a side effect of the pill.

This is colostrum (the fluid that nourishes your baby for the first few days after delivery before your breasts start to make milk). The colostrum may leak on its own or may leak during breast massage or sexual arousal. Early in pregnancy, the colostrum is usually thick and yellow. As delivery approaches, it turns pale and nearly colorless.
