I was using Ovia until I discovered Glow. I like Glow a lot more but I still try to log in both apps. I feel like having more information is better. Well they are currently telling me 2 very different fertile periods. My last period was 3/7-3/11. Glow is saying my fertile period is 3/15-3/21 while Ovia is telling me 3/19-3/24. Right now I have no CM to report. Does anyone else have this problem? Do you think I should just stick with really watching my CM? Or try something different?
