Unusual Bleeding

Th

So to start off I had my “period “ ( at least what I thought was my period ) April 27 through May 3rd . Usually I have a medium flo that requires me to change pads every 5 hours . Instead it was as if I spotted for those days instead .

Once it came to the third , it barely existed ! The forth came and I’m good to go , no more bleeding / spotting . Whatever ! The fifth came , we had sex . I was bleeding because of it . I was wet down there and everything , it felt like he was hitting ( I assumed my cervix ) a few times . I told him to relax a bit and he did . I’ve never bled due to him hitting it too hard .

Today , still no blood . I brought him home from work and things got heated . We ended up having sex again and I started bleeding ... AGAIN . This time it didn’t feel like he was hitting the cervix at all . But i bled , but as soon as I finished showering , it stopped . Has anyone else had this issue ? If so , why did it happen ?
