So confused help please

Taismer

I don’t know why this is happening

One day there higher that other no positive or peak,

I’m supposed to start my fertile window tomorrow but isn’t to far away from period?

I’m not sure if I’m doing something wrong.

Do I have to hold urine before testing like pregnancy test ?

Or I just continue to test in the morning and afternoon until I get a positive

Help help please. I want to get it right this month.
