We hit it raw 😔

So me and my boyfriend had sex but not serious sex, just like he went inside of me for a minute or two and then he started panicking saying that I'm pregnant. He has been saying this every day for like 5 days. And he's saying that maybe the pre-cum Can get me pregnant. But the sad thing is I don't think I can get pregnant..and I was already late on my period before me and him did that. Any advice ladies?
