Weigh In Worries

I've got my weigh in tomorrow and once again the scales haven't moved. I don't know why I weigh myself at home as 1) You're not supposed to and 2) My scales only go up to 22 1/2 stone and then go round again so currently I weigh 3 1/2 stone according to them. 

I really hope I have lost some weight, because I've found this really great free app called TargetWeight. All you have to do is put in your weight and height, then your target weight (I think I put 11 stone), and target date (I put the 3rd July 2014) and it gives you lbs to go, days to go,your BMI, and I think it tracks you weight loss too. I want to update it every Thursday night to track my progress. The BMI box is even colour coordinated to whether you are severely obese,obese, overweight etc. It also shows that I would still be overweight at 11 stone.
