sex on the pill and he pulled out

hi so i’m very paranoid, about a week ago my boyfriend and i had sex for the first time. i had been on the pill for 12 days but we were stupid and didn’t use a condom. he didn’t even get close to climaxing though and pulled out, so i’m assuming everything is ok and there is barely any risk? my period is meant to come in a week and i can’t stop thinking and worrying.
