The 6 week rule comes from the fact that it takes approx 6 weeks for the stomach muscles to fully contract and return to their normal position - this is the reason you need to avoid anything beyond light exercise.

Once you feel comfortable, but personally I would wait a couple of weeks - remember your wound needs to heal and you have internal wounds as well as the external scar you can see.

Take things slow, and go easy on yourself... not quite 'starfish' but make sure you are not over exerting yourself - you will feel in it in the morning

Once your bleeding stops or not - personal choice! lol Depending on how long you bleed. I didn't bleed very long at all after my cs, but the discomfort lasted much much longer.

So anyway, go for your life if you feel ready, but go easy, no swinging from the rafters
