am on full time birth control pills-no stopping for a period. I was put on full time due to very heavy and large clotting periods with pain. Being on full time birth control pills has helped me for over 2 years. I had some light spotting in the beginning and then there after only some spotting if I missed a pill or took one late. For the last year I have been on a very regular schedule of taking my pill on time. For some reason 8 weeks ago I started bleeding and cramping. I had not taken my pill late and I haven't missed any. It seems never ending now. I went to my GYN last week and she did a uterine biopsy-after the biopsy the cramping has gotten worse. I am still waiting for the results and I have a pelvic ultrasound scheduled in a little over a week. She put me on estrace to stop the bleeding but it has not affected the bleeding at all. I am to take estrace for 21 days-last 10 days I am to add provera-then stop everything get a monster of a period she said then I can go back on my loestrin. She says it will "reset the clock". What would cause this to happen all of a sudden when everything has been fine for years? I am 41 years old...
