Scared af

I haven't missed my period yet (it's supposed to start today), but a week or so before I start, my boobs hurt real bad, and that hasn't even happened yet. I've had unprotected sex a couple times but he didn't cum in me or anything, but I'm paranoid as hell. I know it's stupid to be freaking out over the consequences of some dumbass actions, but I couldn't be l more scared.
