Has anyone else notice that the <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">period tracker</a> is way off? Normally it's been fine and my cycle is like clock work always 27 days since I've been tracking with glow. Now this month it has my period to start at 31 days. It's completely wrong. I don't understand why it would change like that without me doing anything. Anyone else have this happen? Because of the period is off so is the fertile week and then that defeats the whole purple is this app. Lol
