first time

it was my first time and we didn’t use a condom. he didn’t finish so there was no semen on me or in me at all. when we first started there was pre ejaculate on his area and i told him to wipe it off before putting it inside. am i all good then? just nervous. i don’t want to be pregnant and i’m pretty sure i’m ovulating right now. he wasn’t in there for a long time maybe about 3 seconds until i told him to take it out. can i get pregnant from that?
