The "Apron" i call it (the flap of skin) is totally normal. It will eventually go away....i still have my apron and my DD is 11 weeks tomorrow.
Even though i have lost 9.5 kilos off pre-preg i still have it but i was big to start with.
As for exercise definately wait till the 6 week check-up and talk to your ob, i waited and have since been doing "Pilates after pregnancy" since just give yourself some time to heal....remember it was major surgery.
As for the colour of your scar mine was purple/blue for the first couple of weeks, by six weeks you could barely see it unless you had a magnifying glass.....everyone is different plus my ob said i had great healing ability.
Basicall chill out it's normal and just give yourself time.
