Are you sure that you don't have some clothes that fit better than before? I have lost 10 pounds recently (I lost some before my ticker.). This morning, I put on some capris that I couldn't button at the beginning of summer. I was braced for disappointment.LOL I was so happy when they snapped. I have kept them on ALL day!
With a 10 pound loss you are doing something right! Be patient and keep at it!
