Just to echo the comments above, it takes time. Any changes you want to do to your body takes time. Want to properly lose weight, that takes time. Those that want to build their physique, that takes time. Trying to grow breasts, it takes time.
Unfortunately we live in an instantaneous gratification society and expect results immediately or many just don't find it worth it. Believe me, if this is something you really want, it is worth the time and patience.
Flame is right, document your progress. You see yourself day in and day out and change is hard to see in ourselves. But if you have something to compare then the change is easier to catch. Even if you decide not to post the pics on here, at least track your progress for yourself.
Best of luck!
