My boyfriend and I were messing around and I gave him a handjob and he wiped himself with a paper towel. The semen didn't really touch his hands. After he used a lot of hand sanitizer and we waited a few minutes before he started to pull my pants down. He performed oral sex on me, not touching my vagina. He only touched it once at the very top. At that time I was done ovulating. Could I be pregnant? I'm really scared and have learned my lesson. It's about time for my period and right now I have tender breasts and feel nauseous sometimes and haven't been eating properly, but I think it's because I'm so scared and nervous about being pregnant. I'm stressing really bad and I think it might cause my period to be late too. Please help, thank you.
