Big baby! What now?

GraceAnn • First baby. It's a girl!
Hey! I just had my doctors appointment, I am 34 weeks 4 days. My baby is weighing in at 7 pounds 15 ounces. In 2 weeks I go to the children's hospital to have a special ultrasound done & then my doctor will decide on delivery options. He said I have a 10% chance of a vaginally delivery. Any mom's have been through this? And what was the outcome?
