Okay so a few days ago I had sex with a new guy for the first time, he's bigger than I'm used to so it hurt pretty bad the first couple of times we had sex, then the next day I went back over and we had sex again and it was kind of rough sex both times, it wasn't as painful this time and I thought I was getting used to it, I was kind of swollen down there between those two days also, but yesterday and today it's started to burn a little when I pee and I looked and it kind of looked like my vagina might be a little ripped, then last night when I went to take of my pants there was blood in my underwear, it was like discharge type blood and when I woke up there was blood in my pee, and I just started a new birth control so it might be just some spotting or something but there's more blood than usual for spotting and I'm kind of itchy down there too and it almost looks like there's like rug burn or something down there, I took a uti test and it came back negative, but I'm worried because there was a rumor about a guy I had been with before having chlamydia but when I asked him about it he said he was clean, I don't know what's going on
