They say six weeks, because that is when you checkup is. They don't want you to hurt yourself, and do something that you shouldn't be-so they use their visit as a guideline.
Your bleeding is definitely an indicator. While you are still bleeding heavily-I wouldn't do too much. (The first two weeks...) After that, I started slowly-with light walking. I added LIGHT weights, and starting doing LIGHT dancing at around 4 weeks pp. Then I slowly returned to normal after 6 weeks...
Your body is going through a lot postpartum-your uterus contracting and shrinking back down, the bleeding, your organs and everything shifting back into their normal positions, hormonal changes...a LOT is going on, so take it easy. Really listen to your body. Also, at this time-consider sleep a priority. If you have not had any rest all day/night, and the baby dozes off-then take a nap!!!! Make sure that you get some rest.
