Ovulation testing

I started tracking my opks this month hoping we'll get our bfp in a few weeks. I'm in my fertile window and got a faint second line yesterday as you can see in the picture. Which I know I'm not at peak yet as the test line has to be as dark as the control line. How many days does it take until I get to a peak test? And when do you usually test during the day? I tested around 2pm yesterday.
