So around the 18th of June my boyfriend and I did make a mistake. We didn't have sex but we were fooling around and he rubbed his penis on my vagina. He didn't ejaculate, and I don't think I was around ovulation time (But my periods are often somewhat irregular) I looked up information on pregnancy from pre-*** and it said it is possible but very unlikely. The only obvious way it can happen is if he has a previous ejaculation and didn't urinate since. I had talked to him about it and he said that he did urinate before this all happened. My period is late. It was due on June 30th and now its July 6th and there are no signs of it yet. The other factor though, is emotional stress. And I also just got off of prescribed Prednisone and its a type of steroid and I'm pretty sure that could effect it too. I guess my question comes down to, in this situation what are the odds of pregnancy? And is it possible the prednisone and emotional stress could have caused the late/missed period?
