Baby's size

Michelle
I just had my last ultrasound. I'm 34w1d. My baby boy is head down! He's measuring really big tho at 37w3d...doctor said he estimates him to be about 9lbs at birth 😬 and moved my due date up 10days from 11/16 to 11/6. I'm really nervous about giving birth to such a big baby as I'm a FTM &I really don't want to have a c-section. 
Also doctor said since baby is so big if I go into labor now he won't try to stop it even tho I'm not full term.
