I randomly had my period for 13 days in the month of September. It was extremely heavy with huge clots. I of course immediately made an appointment. The Dr prescribed me Nora-be 0.35mg tablets 28's. After taking them for almost two weeks it stopped my period by the 17th day of my period. However, I randomly got a sharp cramping pain in my stomach tonight. I go to use the bathroom and behold I have started my heavy period again. I have an appointment tomorrow to get checked for polyps and fibroids but how is it that this medicine is inconsistent. I guess I'm just frustrated of the fact that I'm completely drained and miserable.
