Okay, so me and my boyfriend had sex on July 19th. I was suppose to get my period July 21st. But I didn't, I waited for another day & no period. On the third day, I had finally got my period, but it was very late. I believe when the condom slipped off that cum has leaked inside. When I asked my boyfriend if the condom was inside or hanging out, he said it was inside. He had to pull it out. I'm afraid that I might be pregnant. Can someone please help me?!?
