💢💢Long post warning💢💢

Okkk so I am going absolutely crazy and I need some of you gals advice.....can having covid cause your period to be delayed? I have read so many mixed reviews about it idk what to think..... Af was due 1/21 just confirmed covid yesterday. I was given urine test with bfn results and this month I didn't track ovulation due to waiting on my new test to arrive since they were late this month too... Also my temps have been very wonky but this was first unwatched cycle taking letrozole and I'm beginning to feel very discouraged any help is greatful ladies.... Baby dust to all
