Me and my girlfriend had planned to have a sex. I started to put my penis to her vagina, then after penetration that wasn't too deep, she said it was hurt, i stopped a few seconds and started to thrusting it deeper. However, she said it to pull it out, i did, and full stop. The problem is i keep thinking that is that possible i had a pre-cum and make a possibility to make her pregnant? Now her period is late for 3 days, and i really worried about it, please help us experts.
