This happens to me everytime I go on. I just put on 12 pounds and I don't see a differance. It's only after the cycle when I cut up that I really notice the weight change. I didn't bloat up either. I guess the weight just evenly spreads out so its hard to see where it goes. By the way, be very happy with 16 pounds in 2 weeks. I'm assuming this is your first cycle, enjoy it.
