Tracking after Covid

Hey all! I am new to FAM and have just started tracking bbt and am trying to get a handle on tracking CM. Coincidentally, I started tracking the week after having a pretty serious run of Covid. I’ve been reading that many people are having changes to their cycles post-covid. My period is late (negative pregnancy test), but I’m not sure how delayed things will be. I was wondering if anyone has had this and how it affected your tracking. Thanks! ❤️
