TMI PIC!!!! Blood after having sex?

I've met a new guy and he was pretty rough on me but it didn't hurt as much as some situations in the past. After he took me home I went to shower and I saw this in my underwear. I also was cramping down there and felt very gassy even though I didn't have to fart and I wasn't able to stand up all the way straight because it just hurt so much in that area :( . Was this because he was too rough and made me bleed? I've had some bleeding in the past but never this much. I'm on my fertile week and we used condoms.
