Aww
I had this happen to me as well so I know how you feel. After I lost the first 13 pounds I figured I deserved a nice digital scale. When I first weighed, I was 12 pounds heavier than my manual scale. It was like I didn't lose anything at all even though I know I did
I actually took the scale back thinking it was broken. When I brought the second new scale home it said the same heavier weight. It was discouraging but I went with the new number. Remember that a scale is not the holy grail of weight loss, its only a tool to keep track. Please don't discount your accomplishments. You have came so far already. I would go with the new number but set your original weight 10 pounds heavier so your ticker still shows your loss.
