my Dr tried to do my c Section on my mother in laws birthday ( we dont really talk ) so i cracked it cause i thought i had no say LOL the next appointment i had a bit of a cry and he kinda looked at me weird and asked why i didnt say something earlier . Anyway we changed it!! apparently they can be flexible depending on the hospital but they wont do it before 39 weeks ( at my hospital anyway) unless there is a real reason!
