OPK positive? HELP

Marcela
Hi ladies!
I have a question 
I'm so confused  about how dark the line of the ovulation test has to get .
Glow  days today is the day 
But I don't think the lines is equally dark as the control line 
What do you guys think??
(Yes I took 3 one in the morning another in the afternoon and I just took another one to make sure 🤦🏽‍♀️)
