Sex q

Me and my bf had sex today we used condoms like always but to get him to cum faster I let him stick it in for seconds at a time not even a min without anything on and it was only twice but each time in between I had him wipe it off so there was no pre cum or anything and I'm not fertile or ovulating or anything so I'm pretty sure I'm good but there's no way of pregnancy right ? I kinda stress sometimes but my periods coming in 12 days
