If your breast pain is on the sides of your breasts, this indicates that ovulation has occurred, according to Dr. Jerilynn Prior, a Canadian clinician, researcher and professor of endocrinology at the University of British Columbia. If the pain is in the front of the breasts or over the nipples, this indicates that estrogen dominance has occurred, which may mean the lack of ovulation. If a woman experiences pain both on the sides and in the front of her breasts, this can mean that ovulation occurred but an inadequate amount of progesterone was produced after ovulation so estrogen dominance is still occurring.
