Glow algorithm & clear blue digital ovulation test

Andrea
Has anyone done the clear blue digital test and was the info way different from the glow algorithm?
I am going by the ovulation test more but it is frustrating when I see that glow predicts a window of fertility, then I put in the results from the test, and glow changes the window again!
And it's usually that I've missed at least one of the important day!
Has this happened to anyone else? I am almost ready to give up on this app. It is making me crazy more than helping!
