Cervical position checkers! Help?

Alex • 26. Mommy of one.

I'm due for af in four days. The last two cycles I've been checking during my tww. And usually by now being so close to af, it's dropped down and is firm and has that tip of nose feeling with a small indent. 1-3dpo I thought it felt mushy? And still very high.

However since about 4dpo, I can't even reach it. Anyone have similar experience? Or bfp, bfn results after this?
