Opk help!

Okay so I've never used cheaply ovulation tests before. I tested all during my fertile week according to glow and thats the picture with a bunch of tests. Which according to glow my fertile week ended 2 days ago. I never got a full positive so I've still been testing. Today's tests were darker. I did one in the morning and one at lunch and one this evening. The lightest one is the most recent I've taken. Help me please. Did I already ovulate and miss it? Period is due the 5th. Im so confused.
