Paranoid!!

I need opinions... I had sex yesterday with my bf. Used condom. When we checked condoms there isn't any hols. We check it more times because we really don't wanna baby now. When I checked it (4th time) it has burst. He says that he doesnt cum. Is there any possibility that condom burst while it was in me. But we would see on first check. Okay, thank you Im just paranoid af. My period is due 7days
