I was dry humping my boyfriend and he came. His cum was on a spot on the comforter. I touched it by mistake and then scratched the inside of my vagina is it possible for me to get pregnant? If so how likely ?

Is there a way from stopping the pregnancy that doesn’t involve an abortion?

(I wanna say I had touched the cum after a few minutes and scratched a few minutes after that)

Again I know this is dumb but I’ve been reading that it’s possible to get pregnant like this and that sperm can live up to 15 minutes on the surface so I’m worried

And I’d prefer to not take any medication if there are alternatives
