Settings change from TTC to pregnant by accident. TTC data gone?!!

Sulyn
Please help. I logged my period data for over a year using the <a href="https://play.google.com/store/apps/details?id=com.glow.android">glow app</a> - solely. I use glow to track my cycle days.  I was saving my BFN HPT test to my daily log and it switched over to settings and changed it to "I'm pregnant". I was so confused and immediately changed it back to TTC.  Now my data for my cycle days and period log are gone.  How do I get this back?
