So I've been on my period since about May 9th... maybe even earlier? I thought it was a normal period, and it appeared to end maybe on the 12th... the next day I was sitting down for a long time and felt weird for whatever reason, only to discover that my period came back (and with a vengeance). Since then I haven't stopped bleeding. I thought it was going to stop a few days ago, and then my bleeding got heavier. My cervix seems pretty low, but it's soft and open. I'm still bleeding, so I'm really worried. I have a history of painful cramps and periods in general (ones that are debilitating), but since I've been on the pill, the pain has been reduced (although every now and then I'll have some painful cramps and some migraines too). Help?
