First time using opks...

Okay so I know this is negative but is the test line being so light normal with 2 days till O day according to glow?

This is my first time using these and I never know if glow is right on ovulation or not. I’ve had a ton of raw egg white and watery discharge the past couple days but today seems like there’s nothing really going on down there...

I just wonder if I’ve already missed it or if it’ll keep getting darker..
