So I used an app to help with ovulation prediction to get preg 2 yrs ago and it worked great! Can't remember which it was but I've been using Glow and I've tracked for months now and it seems like my ovulation calculation to predict my peak is off by a week or so! I think! Because I check and 3 times now when it says I'm ovulating, I'm not! I used it last mo, and insemenated and didn't get preg. I tried very close and carefully this mo, and its supposed to be my ovulation days and NOTHING yet again! I'm so frustrated and upset thunking its just NOT gonna happen for me! But all I can do is keep trying! Plz pray for me........
