Zee - I had NO signs of labor with any of mine until actual labor. Well, with my girls, I was dilated to 2cm for a while, but my son was my quickest labor, and as of my last visit, I wasn't dilated. I haven't been dilated with this one, either. She did say I was about 50% effaced, though.
Cinderella - I'm having that same sort of pressure. It's odd.
