There are all kinds of reasons the scale might not line up with actual fat loss. For one thing, it weighs everything without distinction - fat, muscle, bone, water, stomach contents, etc. If you happen to have more water or food in your system or have added muscle, the scale might not go down (or might go up) even if you have lost fat. Weight (on the scale) can fluctuate quite a bit. That said, you probably can't have lost too much actual fat yet unless you were very overweight to begin with. Most people don't lose more than about 1 or 2 pounds of fat per week.
But still, looking and feeling better and having your clothes fit better - that's real progress, and something to celebrate!
