I don’t get it...

I’m lost, I didn’t think this was the month, so Monday comes and I’m expecting AF (which usually comes 2 days before glow predicts) and nothing. I am NEVER late. It’s not Wednesday and no sign of AF. Took a test Monday, negative. Took a test today, I thought I saw something but I’m pretty sure it was a dye run.

Why is this happening?? I’m 15/16 dpo. Anybody else endure the same thing and get a BFP??? I’m so down, I wish AF would come and at least give me another chance it this isn’t it.
