I got precum on my hand from giving my boyfriend a ** ... he never fully came but he did precum. It was mixed with my spit because when I was done I spit on my hand. I quickly went to the bathroom and rinsed my hand off with water. I went for a walk outside and about 20 min later went to the bathroom. I wiped with the same hand but it was dry by then. I didn't touch my vagina with my bare hand but I did touch the toilet paper then wiped. Is it possible I could be preganent ? My period should be tomorrow but most times it comes late and I would like to know so I'm not worrying myself too much . Any imput would help!
