I have endometriosis, and I've had trouble with the first two BC pills I've tried, and now this one is failing me too. I've been bleeding now for three weeks even though I am supposed to be supressing my periods for 84 days, it seems that by the third pack out of four, I start bleeding and it doesn't stop! What makes matters worse is that I get a lot of pain with the bleeding. Lately I've been feeling lightheaded, but today I felt so dizzy I was sent home from work. I don't know what to do!! Has anyone else had experience with extreme break through bleeding? It seems to happen to me on all of them and I don't know what else to do!! (Also, I thought I wasn't supposed to have bad pain anymore after my surgery? ...)
