Disclaimer I’m dumb I know I am please don’t be mean I’m just trying to put my mind at ease and want to ask questions to make sure.

Yesterday my boyfriend and I were dry humping and he came. His cum was all over the sheets. I had touched it by mistake and touched the inside of my vagina.

The cum was out for a few minutes and I’ve read that sperm can live up to 15 minutes out in the open. So my question is should I be worried about getting pregnant?

I also took plan B this morning to be as safe as possible but I’m not sure if it would work cause I might B ovulating ( I say might be because my period is extremely irregular and the cycle isn’t normal ever so there is the possibility)

So how likely would it be for me to get pregnant? And when should I take a pregnancy test? Would it work in 1 week? Cause I read it could be 1-2 weeks so should 1 be fine?
