TMI - Bleeding after sex!?

Heather

So a few years ago, before we started trying for our second child, I had the mirana for bc. When my SO and I would have sex i would bleed after, almost every time. That stopped when i got the mirana out. So.... last night we had some pretty hard sex and he went pretty deep. After, when he was cleaning up he told me "woah, you bled a lot." This is simething he got used to with the mirana and he wasn't really concerned. Almost immediately after, though, my stomach was hurting/cramping. I'm sore today. We have had rough sex before and i didnt have these symptoms after. is this something i shoud be worried about or is this normal??
