Nothing is wrong with you. While you are losing weight, you are also building muscle (this is good) and muscle weighs more than fat... think about it. A great way to see progression is by measuring inches. Here you can actually see the difference. FURTHERMORE, going on the scale everyday is not good for your esteem (even though I do it all the time) Watching a scale fluctuate can be really depressing. What you can do is weekly weigh-ins same day same time. You are doing great... just think of how far you've come so far and keep pushing. :)
