I lost virginity at 13 and since then it hurts to pee, I'm having yellow discharge and sore breasts

So my mother left for a vacation for the week. She left monday early in the afternoon. She grounded me and normally im not the type of kid to disobey her rules but i did anyway so 2 hours after she left my boyfriend picked me up b we went to the movies, we went back to his house cause he "had a free crib" and before we know it its like 10:00 so we start making out or whatever and so we ended up having sex, hes my first im not his though. Ive never " pleased my self" before so my " p***y was tight" so he decided to be rough about things and we ended up having sex a lot today is now thursday and we have had sex everyday since then it kinda burns to pee and i finally started to bleed just a little bit so i thought i must be on my period so i put a pad on a couple minutes later i have yellow discharge and im so confused everyrhing kinda hurts my boobs are sore my gut aches i have no idea what to do. What does this mean ? We used a condom the first time but the rest we didnt but his pull out game is strong asf. So we good im pretty sure im not pregnant and beside he bought me a morning after pill cause im very paranoid. But i an kind of disapointed cause i wanted to wait a couple more years but ig not what do i do? Ive only been 13 for 2 months
