Weight loss plateau

Wondering if anyone else is going through this or if the pounds keep coming right off?! I'm a month pp and I'm stuck at 122.  My pre pregnancy weight is 108, I gained 35 lbs while pregnant with my son. I've lost 13 within the month and I have 14 more to go. I watched the scale go down pretty fast within the first two weeks but now it won't budge, it's stuck on 122 and my pre pregnancy clothes don't fit which is frustrating. I'm breast feeding, and going on frequent walks. Anyone have any tips to get off the last 14 pounds?! Or maybee I'm just impatient lol.
