Went to the doctor today, I'm 1.5 cm dilated and "if she was any lower, she'd be talking to us." So I think that means 100% effaced (and have been for a while). The doctor asked me, randomly, "So do people ask you why you don't look very pregnant this late in the game?" Me: "Uh, yeah, some do." Him: "Do you tell them that half the baby is in your vagina?" Me: "Uh, I'm usually not that blunt, but..."
It was actually very funny, though I think it loses something in translation.
