When I started my account with Glow I only added my last period, average cycle & period days. I then didn't use the app for a while. Now, 3 months further I wanted to back log my periods so deleted the ones in the log as these didn't correspond with the true dates. After I added the correct dates. Unfortunately the future predictions now seem all confused, according to the app I'll be most fertile 3 days after my periods ended (?!) and will get my period again after less than 3 weeks which can't be either... Can you help or should I make a new account and start over? Thanks for your help.
