I’m a bit worried (help!)

alright so i’m trying not to worry myself too much - but I’m still worrying quite a bit.

I’m a virgin (or ..was) and today my boyfriend and I decided to fool around today and he stuck it in a few times and that was really the end of that.

I don’t know if I consider myself a ‘non- virgin’ because he didn’t ejaculate or anything - but here’s why I’m worried:

He came two days ago (masturbation) and since then he’s taken at least three showers and used the bathroom multiple times.

Is there a chance I could be pregnant?

I’ve read up on all of this and there’s a chance that sperm could live inside of pre-cum, but it’s been two days so we should be good .. right?

(Keep in mind I’m not on birth control, didn’t use a condom, and I would actually be murdered |not a joke| if my parents found out I had been doing things because I’m supposed to be a perfect angel - so buying things like Plan B is not an option. I’m also supposed to start my period in about eight days, if that helps at all)
