Breast tenderness. which can range from mild to severe, is a premenstrual symptom. It is also a symptom of early pregnancy.
During the menstrual cycle, estrogen production increases and peaks just prior to midcycle. This causes enlargement of the breast ducts. Premenstrually, progesterone peaks near the 21st day (in a 28-day cycle) and causes growth of the breast lobules (milk glands).
With pregnancy, the breasts are preparing for lactation (milk production). The tenderness is the result of the breast growth and development. Breast tenderness may also be caused by an increase in hormone the levels of estrogen and progesterone during pregnancy, which causes blood to rush to your breasts.
