Ept digital ovulation testing

Justine

Can anyone tell me how accurate these are? I use the ept digital ovulation test and ive been getting mixed reviews on how bad vs good they are. I just started using them last month and its saying im not ovulating at all really. Going to try the strips see if i get different results. Im in my fertile window this week according to the app and i tested today and i was at 0. Advice would be appreciated please!!
