???? Was your 1st pregnancy a vaginal delivery, because if it was your doc would not schedule a csection unless you have a specific issue that would prevent or make a trial of labor and vag delivery contraindicated, you can be scheduled to be induced as the ideal time for the baby to be delivered is 39-40 weeks according to a large recent study, if u had a previous c-sec then u can schedule a repeat.
No. A previous post-dates pregnancy does not require a cesarean section. You may need an induction of labor though if your pregnancies tend to run past your due date, these are usually done after 41 or 41.5 weeks.
