likeliness that I wld get pregnant ? (17 years no BC)

I'm done ovulating and my period is due in five days. I let my bf put it in raw for the first time ever. We did it raw for about two minutes then stopped. There was a point however that he told me to get off quickly and that moment right as I got off he started to cum. I don't think I felt any cum get inside me and I know I'm no longer fertile so it prob isn't likely to get pregnant .
