Measuring 6 weeks ahead! Advice?!?

McKinnize

Has anyone else gone threw this and had their baby before their scheduled due date? I'm only 34 weeks pregnant and due Nov 17th and my doctor said I'm measuring at 40 weeks. I was having some contractions last night and I'm worried that I'm gonna have her anytime.

Is there anyone else out there that was measuring ahead an had their baby ahead or on time?
