Detoxification is a funny thing ... sometimes the body retains in order to do the work. I would take grumpy's advice and lose the scale.
Meanwhile, are you drinking enough of the juice and water during the day? 6 8oz. glasses of lemonade are the minimum. Any less and the body will go into starvation mode - it refuses to lose fat because it interprets the low caloric intake as starvation and works to preserve your life. Drinking water should keep you cleaned out (along with the SWF, of course). If you don't end up losing the scale, you will probably see a chunk of weight drop off in a few more days. It's normal to lose in spurts like that while detoxing.
