Bloody sex and discharge

So i had sex with my boyfriend today, for the past couple weeks, ive been having brown discharge, then today after we finished, we noticed that there was noticeably more blood than usual, like both of my thighs had blood smeared on them, he didn't freak out or anything, we just went to the bathroom and cleaned up. And advice on whats going on down there and what i should do? Should i be worried? We're still pretty new to sex and we've used condoms everytime.
