Why would you be dilated at 37 weeks? That's too early. I wouldn't expect the baby until 40 weeks. Sure, sometimes, they come early, and sometimes, they come later, but 40weeks is average.
Some women go from not dilated at all to delivering I'm a matter of hours. Don't let dilation (or lack thereof) get you down!
I'm 38 week's tomorrow and I'm not dialated either!
