I think for everyone it's a little different. For me at 2 weeks PP I probably shouldn't have but I was doing laundry and sweeping the house, but I also could totally still tell when I overdid it, or when I moved the wrong way.
Now at 6 weeks, I still sometimes feel "bruised" in the general area of my incision, but overall, I feel totally normal again, even went running (even though it was slow), just take it one day at a time, and you will be back to normal before you know it.
