I realize how stupid this is, but please help me put my mind at ease anyways

Lately I’ve noticed I’ve been having nausea so OF COURSE pregnancy popped into my mind, and as a result any time my stomach feels off I think it’s fucking baby kicks 😂 I think I’m being totally ridiculous but I can’t help but be a little paranoid.

I’ve been on birth control for 2 years now, normally I’m good about taking it but since quarantine I’ve become a little lazy at times and taken it 1-3 hours later (not everyday, though). Twice I missed it and just took two the next day. I had sex twice, but I don’t believe either time was around when I missed my pills or took it a few hours late (at least it wasn’t within a few days of those pills).

My boyfriend and I use condoms, and he actually was diagnosed with testicular cancer in June and as a result of chemo they told him he would be temporarily (though possibly permanently) infertile for at least a few months to two years. His last round of chemo was September, so it’s been about 8 months since then.

I’ve been having my periods, but I know with the pill they aren’t actually periods and I‘ve heard horror stories of women being on the pill, falling pregnant, and still bleeding so they don’t know they’re pregnant.

I don’t know why my body’s been feeling weird lately, but of course it was only a matter of time before the idea of pregnancy popped into my head so I’m just looking for other opinions.

I realize I probably sound like a total dumbass, and I definitely feel like one, but I just need some reassurance from others at this point 😂 so let me know what you guys think. Thank you in advance!
