Oh Hamster, I think you should get a tape measure, and try not to rely on a scale if you use one. It's not very accurate especially when you are building muscle at the same time, which is heavier than fat.

Not that either are needed really, you can rely on yourself to know how you feel about your body, I don't think you have body dysmorphia or anything. But if you did want to check than I would go with the tape measure over weighing yourself.
