If you are building muscle you may not see weight loss on the scale but you should be feeling better and clothes should be fitting you better. I haven't taken my measurements since I started my weight loss a few weeks ago, and I don't plan to until I start losing weight and then taper off. Then I hope my measurements will have gone down and will provide me the extra motivation I need to keep going.
If you haven't you should take your measurements, and possibly even pictures so you can compare these throughout your journey. Sounds like you doing well, keep it up!
