I also had a emergency c/s and yep I had the lovely 'flap' of skin that kinda hung over it!EWW!! It did go down but it took a while.I think by the time I was pregnant again with Jasmine it was gone(3-4 months later). I wouldn't recomend doing any exercise till at least you've been to your 6 week checkup and get the ok from your doc. Some scars take longer to heal then others and you don't want to hinder the healing process.
