Yes!!! I have had those days happen a few times since I began. Sometimes, if I wait it out, it means I'm about to drop in weight. Other times, I try to see if I've been cutting down on one food group too much--like protein--and if so, try to increase that. I might be lacking in nutrition! Drinking water can also help.
One thing I do try to do regardless is to make sure that I don't go nuts and eat the wrong foods! Often I still feel hungry, and I'm up too many calories.
Good luck!
