Breast Discharge Some women experience a clear to milky color discharge from their breasts right before the start of their monthly cycle or at the beginning of their menstrual period. This type of discharge is not unusual. It may also be noticed after sexual stimulation or when women begin taking estrogen supplements. The medications listed on this page have also caused some women to experience breast discharge. An occasional small amount of discharge from both breasts is not abnormal. However, if this discharge continues throughout the month, comes from only one breast or has any evidence of blood, contact your physician.
