Hi everyone!

I originally used Ovia, but switched to Glow a few months ago because I enjoy the forums & some of the other features it offers. I still keep all my sex, period, etc. data in Ovia as well. What I find strange is, the predicted periods & fertile days are totally different?

For instance, Ovia is predicting my period to start the 12th of this month. While Glow is not predicting it until the 17th. This also makes my fertile windows totally different.

Does anyone have this same experience & which one do you go by / think is more accurate? 😊

Thanks!
