I have been using the Ovia fertility app for a while now and had a miscarriage in April. :( After that I downloaded Glow and have now been using both. I've been logging my periods and the enter the exact same data into each app but they give me different predicted days as far as what my most fertile days are.  Ovia says I'm the most fertile on the 4-9 of this month and Glow says I'm the most fertile on the 7-13. So idk which to really rely on. I'm also using a digital ovulation prediction kit so that will help as well to determine the correct days but just curious if anyone else has apps that aren't consistent even tho the same data is entered into each one. When I had gotten pregnant prior to the miscarriage I had used the first response digital ovulation kit. I've since used the first response kit again and the clear blue digital ovulation kit (different months) & have not even had a questionable BFP. Any personal experience or reviews as to which kit or brand you've heard works better? Thanks for reading! Good luck to all of you just waiting for that special moment to happen! 😊
