Newest research suggests that elective CS's should be scheduled for 39 weeks due to complications if they are scheduled before then. MMS: Error. If there are no elective appointments available for 39 weeks you could always not schedule your CS date and turn up in labour at whatever date that happens spontaneously. You may have to labour for a little while but at least you know bub will be ready to be born. However I suspect if you don't turn up at 38 weeks for a CS they will find some time to fit you in for an elective. Good luck!
