CD 40 no end in sight

Mackenzie
Today is CD 40 and I've yet to get a BFP or my AF.
We are obviously getting frustrated because I have no symptoms but we want AF so we can begin our next cycle.
Although I have never had the immense amount of egg white cm, actually I've never had it before  (that I noticed) and about 8 days ago I had a lot. And again 7 days ago and it was gone. My luteal phase is usually about 12 days so I'm assuming AF will arrive either Sunday or Monday. With today being Friday. (:
If no AF in another week, I'll get blood work done.
