Growing 2 weeks ahead of schedule

My first due date was may 7, my ultra sound tech said she thinks it should be April 22 and my doctor now says he's considering c-section because baby is so big and would plan it for April 30. I go back to the doctor in a week for a check up and 3 weeks for ultrasound to determine what to do regarding c-section or not.

Has anyone been in this position? If so what were your results?

Also baby was frank breech but turned around I am worried he is. Tech again
