Update:
STILL not dilated, but my cervix is very soft so my OB said it could start opening any day now. She did say that the baby is posterior (yay) and while I was there, my belly was very lopsided and the doctor said that it was the baby's butt that was pushing out. I have dropped about as much as I'm going to, I think.

Oh, and she said that the baby isn't going to be on the small side - she expects somewhere between 7.5-8.5 pounds. Not into the 9+ range, fortunately!
