Period Prediction

Heather

Hello everyone! I'm hoping someone else has run into this issue. For the past 4-5 months my cycles have been 21-23 days. Last month was actually 20. Glow is predicting my next period for September 3rd but that would be 26 days. Has this happened to anyone else? I don't like seeing "7 days until your next period" when really if it comes a day early it could be here tomorrow! Plus I never know when to test! Any insight would be appreciated!
