I’m confused but hopeful

Can anyone shed some light?

I always have a 25 day cycle

Last month I was early and had a 22 day cycle but slightly longer period (6 days instead of 5)

I’m currently at 29 days of my cycle and haven’t come on

I have done two tests, one Sunday and Monday and both negative

I don’t have irregular cycles normally and am never late normally but my mind feels like I’m going crazy 😕
