measuring ahead?

Tyra

I'm 34 weeks and baby is 6 pounds says an ultrasound. My doctor says he's measuring 2 weeks ahead. has anyone else measured large and still had baby on their due date? I'm supposed to have a c section (I have reasons) but I'm worried he might try to come before the c section. I'm also scared I'm gonna have a huge baby. 6 pounds at 34 weeks seems huge
