Just curious to see what you all think my chances of being pregnant are. As you can see... my last period started on December 16th, and I haven't had it since. (Two pics are from Glow, and two pics are from <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">Period Tracker</a>. Chose to show two different apps because they each give me different January period start dates.. Glow said my period should have started on the 14th.)
