My period had always been regular up until I got pregnant and had a miscarriage a month later. I tried different forms of birth control to regulate my periods but nothing helped and after 2 years of nothing I stopped taking birth control. I had about 5 periods in 1 year before it stopped all together for a year; after a year with no periods I started lightly bleeding everyday for a year but 3 days every month the bleeding was heavy like a period. But, after that year went by I've had regular periods, and I can't find a doctor who can explain it. Has anything like this ever happened to anyone?
