period predictions OFF?

Josi

I used Glow <a href="https://play.google.com/store/apps/details?id=com.glow.android.nurture">nurture</a> during my pregnancy and am back to the normal (purple) Glow. It says I had a cycle that lasted 371 days and now my average cycle predictions are WAY off. how can I fix this??? sincerely, my cycles are only 26 days 😂😂
