Confused with Glow cycle and my CM telling different stories?

I know that I saw EWCM and figured I was in my fertile window. I'd had slippery for a few days before that. It was a week before Glow said I'd be fertile, but i figured I'd trust my body as opposed to the app. I didn't use OPKs because I'd been getting discouraged. After my EWCM it became thicker and white so I figured I was correct.

Now, I'm 4 days late with negative tests and now I have a lot of CM that's white or clear. I'm so confused. Was Glow right about my fertile window? Am I right but wait a few more days to test? Maybe I'm just now in my fertile window? I'm never not using OPKs again!

Does anyone have any thoughts? Thank you!
