Post partum weight loss plateau

Options
Hey all
How have other moms dealt with the weight loss plateau? I gained 30 lbs with my pregnancy and got up to 192lbs, 5ft 8 inches. I was 175 lbs by three weeks post partum and the scale hasn't changed regardless of diet or exercise. My shape has slimmed a bit but the weight is stuck at 175. I just stopped breastfeeding yesterday (really rough go with low milk supply and feeding issues). My baby is 4.5 months old. Any suggestions? For any moms that stopped breastfeeding, how long did it take to lose weight after that?
