Hi. I have my last period on may 7th-11th. On june 2nd, my boyfriend fingered me only right at my vaginal opening, not going inside. It happens only like 15seconds. Before he fingered me, he touch his penis not directly, it's inside his pants. He haven't ejaculate yet, only precm. After that he wipe it on my underwear, then start fingering. I am sure i don't feel any fluid/ wetness on his finger. right after that, i wipe my area with toilet paper and wash it with water. Is pregnancy possible? Thanks before.
