New to this, does anyone know what my cm may mean?

Hi! This is my first cycle ttc, so I'm over looking into every sign and symptom, lol. I'm tracking my cm to know when I'm ovulating, and tracked that I ovulated about 7 days ago. My cm after ovulation thickened a little and turned more white, then yesterday it was watery. Today it is VERY thick and lotiony. It seems like it is all over the place... Am I reading it wrong or something? Please help!?
