Hey China,
Have you tried on any of your "tight" clothes recently? (I am assuming you have a closet full of different sized clothing like I do). Or even go to the store and try on an outfit. I think you'll find that you've probably gone down a size. While you may not have lost much weight, you are building muscle mass with your workouts. Muscle weighs a lot, but it will help you to burn more fat as you continue your workouts. Sometimes the scale isn't the best indicator of your progress. Keep up the good work!
