rough?

I love rough sex. Hardcore. Hair pulling that clapping noise sex. But I decided to be celibate for awhile but I had an oopsie slip up and had sex with a coworker. I didn't cum like normal. I actually squirted and it didn't take long. My couch was covered. Anyways. I went to go pee and it burned really bad. That's normal right? I think so. After rough sex I think it's like that I just can't remember but also if he came inside of me and my fertile window opens in 3 days is there a chance of pregnancy? Just last well this month I had a weird period and almost thought it was implantation bleeding. Help! Please?
