Pregnancy?

I had just got off my period on the 1st and on the second I had unprotected sex. It wasn't for very long, maybe 3 minutes. I was intoxicated and so was he and he did not cum inside me. I know all unprotected sex is risky but I'm just wondering what people's opinions are on this. I have never had unprotected sex before and I am just worrying about it now. Thanks🙊
