it sounds like you may still be eating at a *bit* of a caloric deficit--> not enough to see a real change on the scale, but enough to keep you in a glycogen and water "depleted" state..... obviously after all your hard work losing you dont want to see the scale go up, however, once you reach your "true" maintenance cals, your weight SHOULD go up ( ie; that 2-3 pounds it sounds like you know to expect). Its just water and glycogen, of course, but it does need to happen.... you cant stay in a deficit forever, KWIM? Even if you arent meaning too....
Id continue to slowly increase those cals till yuo reach that state.....
