Ovulation test

Nat

I stopped taking my birth control and got my period in 2.8.18 till the 5.8.18 and I been checking my ovulation since 10.8.18 and all the tests are negative, so I’m updating the app every day and the ovulation time change every time 😕

In The last few days my breasts are sore..

Why the ovulation test aren’t working??
