Protected sex

My boyfriend and I had sex last night with a condom. When we were going at it last night we were fine until I got on again and the condom slipped off and we did it about 3 mins and I got off because I got a cramp. Then I made him put on a condom again and I got on again until he cummed in the condom I checked it and everything looked super fine should I be worried about getting pregnant if we did it for about 3 mins without and also it’s 2/3 days before ovulation
