should I be worried about pregnancy?

I’m on the pill and take it within 15 minutes everyday, never missed a pill. I had my withdrawal bleed last week and had sex once during my withdrawal bleed (with a condom) and then once after it was over (also with a condom again). and I tested both under water or with air and didn’t detect any holes. if the condoms pass either one of those tests, does that mean they definitely didn’t break? i just get nervous :(
