Hmmm little tmi

I'm 14 dpo. AF due tomorrow....  Mild cramps, nausea (about a week), insatiable appetite. My CM earlier was watery. Enough to where I could feel it come out. I thought AF was gonna start today cause I had some spotting early evening so I put in a tampon about 3 hours ago. I just changed it and it's fully wet, but only the tip had some blood (like nickle size) but also had EWCM. Anybody have this before? Maybe I have and never noticed it, but I don't remember EVER spotting. I'm certain AF is gonna fully kick in over night ?
