Brown discharge ?

I had sex 5 days ago and I lost my virginity and I bled. But it’s 5 days later and I’m having brown stuff in my underwear. And my vagina kind of hurts. We had unprotected sex btw, idk what it means help ! And I’m ovulating right now I’m not sure if that’s why like maybe I’m just reading into all of this too much. But I don’t have my period for another 2 weeks
