Glow App not accurate

Leah

Are anyone else’s predicted days so far off of what they actually are? We’ve been TTC for a while and we are using ovulation tests and the predicted ovulation time that Glow gives me is off by more than a week. Even though I’ve input my ovulation tests, Glow hasn’t caught up with my actually cycle. And my cycles for almost a year have ranged between 28-34 days and this month Glow is predicting that my cycle will be 27 days long. What?? So weird.
