I’m scared

Okay so, not long ago me and my boyfriend had sex, we hit raw for a bit then put a Condom on, few hours later it sorta just happened and we hit raw for like 20 secs then put a condom on again, I was sorta scared considering he had already came but he wiped his dick? I’m late for my period by 6 days, but we had sex 1 week ago ? Idk what I should be doing and should I be scared?
