Help ladies!

So! I went from really watery cm during my fertile glow window then maybe three days later I had thick egg white jelly like cm then back super watery now it appears to dry bc I been out all day nothing in my panties ! I have mild AF cramps and back pain headaches n mild but noticible tiredness but that's it! Expected AF according to glow is 10/22/14. Are these early signs of pregnancy?
