So this started while having sex. I thought I was squirting, but I actually accidentally peed on my S.O.'s member while in doggy... well he was concerned because I was hunched over in pain and groaning and he decided to clean me up first. Well when he wiped me off, he said that there was a very light amount of blood. I went to sleep shortly after and I slept from 6 all the way to 1015 tonight. I went to the bathroom again after I woke up. When I wiped there was more blood than when he wiped me off. I wiped twice to be sure. What could this be?

Additional information: we always use the pull out method; I'm not on birth control, but I used to be and I'm still regulating from that (stopped taking bc in December); I've had my period already this month.
