I don’t think my ovulation tests are getting darker

Jenny

I miscarried in February, I used the same tests to conceive that baby, I actually would get a peak.

This month and last month I haven’t had a peak, glow says I should ovulate tomorrow with having a peak today but I tested and there’s no where near a dark line. I just don’t know what I could be doing wrong. I test twice a day from 1-8pm

Here’s my test from today and the other day for reference
