Hi
i felt exactly the same i did a week in dark purple then was really naughty one day and threw myself out of it,it took 4 days to show ketones again so im not cheating again.
the ketostix are not as dark as they were before but i know im loosing as my trousers nearly fell down yeaterday.whoop whoop
i just use them now as a bit of incentive to show im not going over my carb allowance.
Regarding the scale not moving and these stalls ive been told on here and read other peoples posts and yes they are all right you can loose inches and not weight,as my scale is moving to much but i like how my clothes are hanging.
Hang in there and your in the right place as whatever your worry everyone here will help.
