Ovulation

Cathy

So I have been using this app to detect ovulation day since June last year, and I have been trying to get pregnant but no luck, then I bought the Mira fertility budget, I have been testing my urine for LHhormone. Today the app tells me am ovulating but Mira tells me the hormone is not present, am confused.🤔🤔🤔🤔😢 any clarification?
