Where you generally lose weight first is the place you least want it to go!! I noticed that my face didn't look as puffy (YAY!), however the most noticeable thing was the room in my cup size!!
I also noticed that there was slightly more room in the legs of my work pants.
I lost 4 stone prior to this time (I have maintained that loss), but I had a photo taken every month at the weight loss club....that was when I started to notice subtle changes.
Don't worry too much though because you'll soon notice changes. Remember that the weight loss distribution all evens out in the end.
