Please help

This is the first time I have ever tried to track my CM for fertily well it was the night before I prodicted having the egg yolk CM I know TMI I had sex. the next morning I wake up go to the bathroom and its in my underwear and it's not all clear it's clear and white almost marble like. This is probably a weird question is the normal or just a mixture of him and i? I have never had that happen before. And sorry TMI
