I started my period and a new birth control on February 19. The first few days were extremely heavy and excruciatingly painful. Although it has gotten lighter, I am still bleeding today (march 4) and am experiencing odd pain in my stomach and pain in my lower back. I am exhausted constantly, my bowel movements have almost stopped, it is painful to press on my stomach or have intercourse. I have a history of ovarian cysts and a family history of uterine cancer. I don't want to worry needlessly, but I also don't want to ignore something important. Does anyone have any thoughts?
