I'm confused on CM

So I'm 6dpo now and for the first 5 days I had a lot of creamy cm and I just checked it and it's watery with a tinge of mikyness to it. my cervix is also kind of high and medium firm but it changes throughout the day. I've also been experiencing mild cramping in my lower abdomen region and hips, my boobs have sore the last 2 days and I've been experiencing some nausea on and off for a few days. I'm confused as to what could be happening, I've never had this happen before.
