So me and my ex boyfriend had protected sex on New Year's Eve but he said he didn't even cum it was pre cum and that he had the condom on the whole time..but on January 20 I had protected sex with a guy he says he used the condom correctly and that there was no holes and it didn't break but I'm three to four days late should I be worried ? Or is it just the stress making me late ? Is it because I had sex so close to when I was supposed to start?
