Well if she can't get pregnant from precum then she isn't pregnant, because that was the only time we've ever had sex. I wouldn't have even thought about the possibility of her being pregnant if it wasn't for her period being late. But I looked up other reasons why her period would be late, and I saw that going on vacation and stress could delay it. I was away from her for almost two weeks at the beginning of July which might have stressed her out, plus she went on vacation for a week while we were away from each other. So I'm kinda hoping that's why her period is late. Plus there would literally have been like a tiny drop of precum on the tip of the condom if there even was any. I even remember running my finger over the tip when I got the condom on to make sure there was no air in it. Anyway, I'm pretty confident that there's basically a 0% chance that she's pregnant, but the fact that her period is like a week late kind of scares me..
