Ovulation tests...

So for the last 6 days I've been on my fertile period. I've taken an ovulation test everyday, but according to the instructions because the test window is not as dark and the control window I have not ovulated. Glow is telling me today is my most fertile day, my test still looks lighter than the control so I don't know what to think! 
​I know you're not meant to stress yourself out with stuff like this when TTC but this is stressing me out! What if I don't ovulate?! All I want is a family why is this so hard?!
​Thanks for listening ladies xx
