Lost few inches but weight remains the same though i m really overweight?

Actually my height is 162 cms and my weight is 73 kgs. Actually didnt reduce much after delivery. Now i m working out and trying to get back in shape. My lower abs, hips and thighs have really become flabby. I started almost an year before and reduced only 4 kgs in 8 months. After that i oscillate between 73kgs to 74 kgs for the last 4 months. But in this four months also i have lost few inches but my weight remains the same. I m following a healthy diet too. Drinking plenty of water. I was somewhere near 65kgs before pregnancy. Its really demotivating to see the scale ticking at 73 or 74 even after doing things right.. Is there any way to come near 65 kgs again. Pls let me know if possible and help me get motivated.
