Need help ASAP

Okay so my period started dec 1. I had sex for the very 1st time on dec 7th with condom but my boyfriend went it without condom for about 3 mins and then put a condom back on and that night her never cummed the next day. Dec 8 we had sex again but this time with condom, then we had sex again on Wednesday dec 12 and the same thing happened the 1st time but this time he did cum but he had a condom on. What I’m scared of is that the last time we had sex was 2/3 days before my ovulation im worried I might be pregnant since he was in me without a condom twice for 3 mins but hadn’t cummed before should I worry?
