6 days late for af, heavy Cm, hard cervix?

What is going on?

I normally dry up right before af, but I haven’t, not even close. And normally your cervix is low, hard and open right before af, but mine is hard, high and closed, which is weird, I’m 6 days late, I’ve had some light cramping the past view days, and negative pregnancy test. What is happening?

My body seems completely out of whack
