Happy Anniversary! Don't worry about the scale number, as long as you are always using the same scale the difference between early readings and later readings will be accurate enough. I gained weight early on too, but I could see that I was smaller. Muscle weighs more than fat by volume. It is a good thing, gaining muscle. (makes for beautiful curves!). The weight will come off soon enough! Sounds like you are doing great!
