Will glow suggest when to take a pregnancy test?!?

Courtney
Hi girls,
​I'm wondering if glow will tell me when I should test or if I should just go based on my own calculations?
I believe I ovulated January 1st and AF is due the 16th. I was planning on testing the 15th, but am getting very anxious!!! 
Any suggestions!? 
​Thanks ladies! GL to everyone!
