Quick question!?

So this I was suppose to start my menstrual this morning & I unusually start in the middle of the night but woke up this morning.. nothing but they thing that caught my eye is the CM.. there was a nice amount when I went to use a plug (I’m getting ready for work and I’m preventing and potential accident) but the color was literally egg shell white and it was creamy 😩 what does this mean? It’s suppose to be the first day of my cycle but instead there’s just discharge 👀
