So I have 3 period tracking apps, Lunar which says I'm 4 days late, Glow which says I have 2 days until I start, and Flo which says I have 8 days until I start. They are all set up the same cycle days and length and everything. Should I just delete the other apps and keep this one? I just don't know why it would be so off for when I'm supposed to start if they all have the same information. I'm just very confused. Lol
