I was with someone and we were involving ourselves in sexual activity. He would finger me, but I refused to do anything towards him. One day, I had on my underwear, but was on top of him. Somehow, he took his penis out and tried easing his way into my vagina, but I told him no. He did not stick it in, but possible the tip went in. He continued to try, but I said no repeatedly and left. I stopped talking to him. Maybe 5 days later I was hanging out with my friend of 5 years. One thing led to another and we had sex. He said he pulled out and caught everything in his hand. I later we realized the day we had sex I was ovulating. We didn't use a condom and I wasn't on birth control. I also have never taken an emergency contraceptive. I am now pregnant and worried that I don't know who the father is. I am hoping it's the guy who is my friend that I actually had sex with and not the guy I repeatedly told no. I was very sure it was my friend's baby at the time since he was the one I had sex with, but as my due date approaches I'm getting more and more worried it's not. Is it possible to get pregnant by the guy I told no?
