cervix position

Okay ladies.... now I'm totally confused. AF is due today (I got BfN all weekend). I checked my cervix last night and it was high and soft. I thought it was strange but I promised I would wait to see what today brought. I checked this morning and it was low and soft- I thought that AF was for sure coming. But I just want to the bathroom and checked again and it almost so high that I can barely touch it. And it's soft still. Any advice? I am sooooo confused!!!!!!!!
