Initial time for a fracture to get back is min of 4 weeks but your bone wouldnt be ready yet. It takes 6 months for the full recovery of the bone. If you put your wt before the proper "cementing" of the bone tissues it could lead to "bending" or "malalignment" of the part. Suggest you to take ample rest, followed by fresh vegetarian diet
(improves healing faster) and just isometric exercises with slight weight bearing during walking. Yes you can work while sitting as long as you are not stressing your leg.
