Hi.. Based on your last menstrual period, the probably due date should be 4th june 2010.. Opting for the cesarian section is your choice.. However normal delivery can happen if there previous scar is healthy, with no dehiscence and is located at the lower uterine region.. It also depends at the time of delivery, there are chances of normal delivery if the above criterias are fulfilled and if there is no complications either to the mother or to the developing fetus.. This will be decided by your treating doctors at the time of delivery.. So follow with your doctors...
