I am 45 and have been experience vaginal bleeding for 45 days. I have never had problems with menstrual periods prior to this but my doctors have found an on again, off again ovarian cyst. My doctor put me on birth control pills 30 days ago and I am now in the "menstrual period" phase of the cycle. This morning I had an unusually heavy flow and what looked like a deflated flesh balloon discharged. Otherwise I haven't experienced any cramps or pain. Should I be alarmed? Any idea what this may be?
