What Causes Pain In Vagina After Sex?

Hi, I had sex with my boyfriend this morning and immediately after my vagina had sharp razor blade like pain when I peed after. The sex was kind of rough and I'm afraid he might have torn something. I was just wondering if there was an advice. There was some blood on the condom and there was some muscous that came out when I peed later that day that was light brown. Please some advice?
