Someone just give me an opinion

My boyfriend and I had sex 2 times today and my period is supposed to come in 2 days. We had protected sex the 2 times and the condom didn’t break (he pulled out too). My chance of pregnancy is 3% today, but I’m not really worried about that since none of the condoms had leaks. I’m just worried that sex may delay my period. What do you think? Also if you want, just confirm that my chances of pregnancy are 0% lol
