Where is the weight loss in my stomach

First, it sounds like you are an apple shape, which means your stomach and arms will be your first place to gain and the last place to lose. I am the same and yes, it does suck. The good news is that the more you lose the more you will notice in those places so you are probably right about to see a more regular drop in those areas. If you aren't already, keep track of your measurements. You will see progress on the tape before you will even notice it in pictures. This is at least my experience from before my last pregnancy.

Secondly, if you haven't started doing strength training yet, make sure you incorporate that into your workouts as well. Strength training has a way of changing your body composition more than just cardio alone.

Great job on your weight loss! Don't get discouraged. You will see loss in those areas if you keep going.

Waist fat for most is usually the last to go. Continue on.
