Data Went Missing?

Cindy
Suddenly all of my fertile windows and previous periods aren't showing on my <a href="https://play.google.com/store/apps/details?id=com.glow.android">glow app</a>. I track BBT and it still shows that part as well as my daily log information so I'm not missing everything. Is there a way to get the information back? I go to the doctor to discuss my tracking next Wednesday so this is a really bad time to lose all of this information
