Too Rough? Maybe 🤔

Ok so last night me and my husband were doing the dirty he started with fingers 🙄 moved down to give me some oral 😱😛 and ended up pounding me so hard 😳 It was great But here's the thing after we were done I noticed dark blood coming out infact when I first went to pee this morning there was still blood my period isn't due yet I have 10 more days and I'm cramping is that normal? Maybe the sex was too rough I have the copper IUD
