Worth another test?

I’m currently 9 days late, I tested negative at 8 days late. Still no sign of period coming, and was recently diagnosed with covid. I’ve heard of people mentioning Covid has had a negative effect on their cycle, but is it true? We used two digital tests (he grabbed the wrong one lol) and they came up negative, but I read somewhere that digital requires more hcg to be accurate than the regular test.
