Are you exercising at all? Losing inches = losing fat, and maybe you're gaining a bit of muscle? Muscle is way more dense than fat so you probably wouldn't see the change right away.
I am also losing inches faster than actual pounds. I only started a few weeks ago, but I got spoiled with losing large amounts my first two weeks. Then I only lost 2 lbs but like 5 inches total everywhere. My coach warned me this would happen around week 3-4 so I'm not too concerned at the moment.
Don't get discouraged, give it a little while and see what happens. As long as you are losing inches, it's still progress for all your hard work! And you get to wear new clothes soon!
How you look and feel are just as important as the number on the scale. If you are losing inches you must be doing okay, and congratulations are in order!
