Incompetent cervix

I am 21 weeks, my cervix is measuring at 1.1cm and funnelling. I am on progesterone and bed rest. I am also experiencing Braxton Hicks.

I constantly feel like I can feel my cervix. Like I am aware of it’s location inside of me and it’s as if I can feel it opening like a nagging itch. Has anyone experienced this? I’m very worried that I could be starting to dilate. Any one experience this???
