My doctor wanted me walking as soon as I had the catheter taken out. And then usually for vaginal deliveries you want to wait 6 weeks, so for c sections you may want to wait longer. If you over do it, it can effect your incision and also your post partum bleeding. Basically listen and pay attention to your body and do not over do it. I'm almost 6 months post partum, and I still have pain every once in a while.
