I haven't had one I have had 3 friends that have, two had perfect c-sections that barely scarred at all, one wasn't quite so lucky but she did more than she was supposed to have combined with the not 100% perfectly done stitching led to her ripping some of the stitches and needing another hospital visit, but it probably could of been prevented if 1. the dr had taken more time and 2. she hadn't pushed herself.

These are all recent as well. The fact you've had 3 good ones thus far I really wouldn't worry just sit back and relax and make sure you don't push yourself too mch too early

Best of luck for a happy and healthy bubs and c-section *hugs*
