Stages of cervical mucus

Lindsey

So, last week me and my husband BD and then the following day I had a clear CM, which was a couple days outside my fertile window according to Glow. We BD a few days later. Today, at the end of my window, I had thick creamy CM. What are the stages?? Was I fertile with the first mucus? Does it get thicker before it gets to EW or does EW come first before thick/creamy??
