text: i am having trouble regulating my period since i got off depo-provera.....? should i take birth control just to re-regulate my period? i have always had problems with hormome therapy including birth control, but it has been nearly two years since my last shot and i still only have very light periods every few months. i have a mitro-valve prolapse and migraines so i was told i can't have estrogen in my birth control, they have to be progesterone only. any suggestion? experiences? ask a doctor
