Cause of missed period?

I know I’ve posted already but I’m pretty worried. So I started thinking about what could be delaying my period.

Around a week and a half ago I had the stomach flu (around my ovulation time) so I’m wondering if that could have delayed my ovulating (bc right now it seems like I’m ovulating but I can’t really tell)

Another reason could be the amount of stress I’ve been under. I’ve been having mental breakdowns often (I suffer from Severe anxiety and depression)

Me and my boyfriend had unprotected sex maybe 2 weeks ago? He never ejaculated (I hate that word) inside of me but im still kinda worried, I’m taking a pregnancy test soon but I’m waiting a few more days to see if I get my period

(My period is often irregular

Example: 3 months ago I normally got my period on the 18th, last month I got it around the 21st)
