Hi Dusty.. my oldest DD was 20 days overdue when my watres broke and after being induced (exactlly what we tried to avoid, just labour never rreally started)22 days when she was actually born...we had daily monitering and the last few days 2 times daily..she was well cooked and like someone else said it took a long time for her flaking skin to settle down plus she had lost weight was long and skinny with lose skin..you could see she would have been a bigger bub..the placenta was in bad shape..I don't think I would have allowed myself to go that far over again..
My next daughter was 14 days over..she bet an induction by a day..she was great and a big girl ( had grown heaps in the extra time she was in there) placentas was pretty good as well..and my last DD was 7days over I ended up choosing the CS..(which was ver likely to happen anywy) in the end I just wanted a healthy bub and had started to get very nevous that something could go wrong..
Goodluck with whatever decision you make....you have to be comfortable and feel confident and make sure there are lots of movements..I reckon bubs will make his/her entrance soon.
