2 days before AF Starts?

I have a question its 2 days before AF starts (On Friday 15th) and I'm still seeing milky/Creamy texture CM? Does anyone know what that means?? Glow told me to test yesterday but I don't want to test until after the 1day of my missed period, in the past I have always got my hopes up to get a BFN 😞
