Recently, (about 5 days ago) me and my boyfriend had sex. It started off with a condom, until he ejaculated in it, and took it off. He then wiped his area with a towel, and we had intercourse again, unprotected. He didn't ejaculate inside of me, but could I be pregnant from leftover sperm or pre-cum that he may of had on himself? I was supposed to start my period yesterday, and I'm stressing so much about this. I usually have symptoms before my period starts but there's nothing. Do you think I am pregnant?
