Am I pregnant

I’m freaking out I had sex 3 weeks ago we used a condom when we did had sex I was 5 or 6 off my period that time the condom came out but it ended up being inside me but not deep in side. We checked it no hoes was up there and he already came twice before the condom got stuck. I didn’t take a plan b because when we usually have sex he can only cum 2 rounds. So I was thinking I’m ok now that my period is supposed to be in 2 days I’m a mess I’m scared I keep thinking it’s not going come I was cramping for two days but now I’m not getting any period symptoms anymore. Could I be pregnant btw I had sex 4 days ago we used a condom
