Hi. I had sex with my bf two weeks ago. We used the protected condom while having sex. Before he ejaculated his sperm, he will always pull his penis out from my p***y and do the business with the condoms on. And now, my mensus is 13days late. Why is that so....? I dont think that i am pregnant. And my pee hole is hurting. Im just so worried. Issit because of being too stress? Can somebody help pls...
