Where is my period, Covid?

Anyone else having irregular periods after covid or loose their period entirely due to covid? I had my last period right before getting diagnosed with covid early November and haven’t had it since. I’m over 2 months late and definitely not pregnant (on IUD and took 2 tests both negative). I used to be pretty regular and even tho drs say most women stop having periods with an IUD,

it’s been a decade and still had periods until now. The weird thing is I feel like I’ve been perpetually having pms symptoms like a pre-period Groundhog Day, that can’t be normal right? 😅😂
