I have been on birth control for almost three months now, and the doctor told me that irregular bleeding and spotting is common in the beginning while your body adjusts. But three Saturdays ago, November 10, 2012, I got my period weeks earlier than I should have. I expected it to be my normal flow and after a few days be gone, but it hasn't stopped. Last Saturday it seemed that it was ending, but now it is heavier than ever and I am seeing huge blood clots when I use the restroom. I go through 4 Super tampons in a matter of hours. I have become exhausted and drowsy, with constant headaches that I have never gotten before. Please respond if you know anything about this. My OB/GYN is closed until Monday and I am really becoming concerned.
