More weight loss

So I decided to see if I had gained any more weight than the 2 pounds that I gained back of the original 20 I lost.  Well...in the middle of the day after having eaten some the scales shows 4 pounds less than the other day.

OK, so now I'm down 22 pounds.  What the heck?  Our last u/s was about a week ago and the babies were measuring at 9oz and 10oz so I know they're getting what they need.  What's going on with me?
