Glow App Help!

Erin • Wife. Mom. Potter Head. ⚡ 3 lovely girls 10/25/13 -- 04/05/19 -- 09/10/21 ❤ #4 BOY!!! due Jan 25' 🧡

I started my AF almost 3 days later than usual, and have logged as so each day but the app never changed itself and now it has taken away ALL of my future predicitions of periods and ovulation/fertile days. HELP!
