Another thing; since you have carried successfully to term before, it is to your advantage and less likely that there will be obstetrical reasons for a c-section (unless you had them before). I am sure you know to expect the unexpected, because stuff happens regardless of your intestinal plumbing.
I had a c-section with my first son, long before I had any abdominal surgery. He was breech and it did not occur until I was in labor. But, since you are experienced with pregnancy, at least you have that going for you!!
