Okay be and my boyfriend were messing around and I gave him a bj. He came and he wiped everything off good and made sure there was no semen left. We waited about 10 minutes then we started to have sex. This is my first time and he used a condom. After about 30 seconds he took the condom off and we had sex without it for about 10 seconds. He didn't come at all. But im afraid that some semen from when I gave him a blowjob got inside of me. Do you think I am pregnant? I had my period about a week and a half ago.
