Bleeding after an orgasm

This is just freaking me out. I've been pregnant five times before and I have NEVER experienced this!! Like everything about this pregnancy is just a straight freak out, is this normal odyssee. So my guy and I have a lot of sex and 90% of the time I orgasm unless I have a mental block. Well I noticed that since I've been pregnant every time I orgasm I bleed. At first I thought it was penetration but tonight I told him I wanted to "do something different" and we made each climax without penetration. Well wouldn't you know, I go to the pot and there is this funny colored red blood when I wipe like the other times when he penetrated. What is going on and when does it stop?!?!?!
