Losing inches, not weight. Why?

I'm not sure why, but girls seem to have a hard time wrapping their heads around this very basic concept.

You don't have all that much fat to lose, so virtually anything you do will build muscle more than lose fat. Since muscle weighs more than fat, your weight won't change and might even go up. This is NOT a bad thing because muscle is GOOD. You can tell you are losing fat because you are losing inches, but the fact of the matter is the more active you get, the more muscle you pack on. And since your weight is not a measure of fat, but a measure of your body's water content, fat content, muscle content, AND bone, if one goes up while the other goes down, your weight (the total of everything put together) won't change much.

Again, this is NOT a bad thing. It is, in fact, a VERY good thing.

As a woman your body is meant to have a more significant amount of fat on it than a man's. Your body depends on maintaining your fat above a certain level to keep your hormones regular. Therefore your body will fight to hold onto fat now that you've gotten down to the point where you don't have much less to lose, because it HAS been proven there is a link between your body's rate of estrogen production and your level of bodyfat. More fat = more estrogen production.

I understand what that frustration is like. The real truth is harder than just osing some weight. I think you look great already from your pictures, but the way we see ourselves is often distorted in cruel ways. Even when I was in the best shape of my life at 18 I found things to be unhappy about. It's also what the others are saying about building muscle.
