My cervix is popping out of my vagina!

Elise
Okay, so I'm a little over 30 weeks and I've recently noticed when I squat or use the bathroom that my cervix is right there at the opening of my vagina! It feels like so much pressure but doesn't necessarily hurt. Has anyone else experienced this?? What did your doc say?
Btw - I have an appt coming up so I'm getting it checked out. I'm just curious if any of you ladies have gone through the same thing. TIA!
