Paranoid?

So, I know this is probably just me being paranoid because I do that sometimes, but during my fertile window my boyfriend fingered me, touched himself, and fingered me again so I’m unsure/worried he may have gotten precum inside of me then?

I’m not getting my period for about another week but I’ve been extremely hormonal lately and I’m worried it could be pregnancy.

We’re not sexually active other than oral and such, both still virgins, but I tend to get paranoid and I would just like a second input on this. I know the odds are for me not being pregnant by a long shot, but like I said, I get paranoid.

I know how the body works and how pregnancy works, but I also know there have been extremely rare cases of pregnancy without sexual intercourse.

So, am I paranoid or do I have a logical reason to worry?
