I'm 17, and I was freaking out for about a week, my boyfriend and I had oral sex last 11th of December, We tried the 69 position, he doesn't came in near or inside me, he came at his stomach. But I played to his sperm and lick it by the use of my finger, after that I washed my vagina and finger. It was followed 13th of December, we did it again. Oral sex again. He came on his stomach. And I wiped it out with a tissue and after I wiped it, I sprayed alcohol on my fingers just to make sure that there's no sperm left on it. I was at my ovulation date that time (according to the app that I am using) I'm freaking out since last week, cause I feel dizzy. I do not vomit. I searched some pregnancy symptoms, and some of them, I have. So my question is, does fingering with a stray of sperm on finger can cause pregnancy? Can 70% alcohol kill sperm? And what's this feeling I'm experiencing? My period is in 3 days. And I don't know if I'm pregnant or just PMSing because my period is in 3 days. It would be nice if someone will answer my question. It is a big help. Thank you
