Take a breath and relax. Your weight loss will fluctuate. As long as you take your vitamins, eat your protein and drink your liquids--you'll be fine. Don't be discouraged when you don't lose as much as you think you should lose. As long as the scale keeps going down, you're going in the right direction.
