Putting on too much weight but not showing it?

Question:

I've always been my ideal weight, up untill last year when i started gaining. i'm now 2 and a half stone over my ideal weight, the thing is i havent changed my diet, i havent grown im not pregnant and theres nothing medically wrong with me.
What im wondering is why is the weight not showing, im still the same dress size and look no different. could my scales just be wrong? Its just really bugging me coz im expecting to wake up one day with a huge belly!!

Answers:
You must be turning fat into muscle because muscle weighs twice as much as fat.

If you are young, your body metabolism is alot faster than people older than you are. Your body tends to burn the calories you take in even if you do not have exercise. The basal metabolic rate varies from person to person. If you do not experience signs and symptoms such as heat intolerance, fatigue, palpitation and menstrual irregularities all of which points to hyperthyroidism then you are fine. Hyperthyroidism presents with a hypermetabolic state wherein a person does not gain weight even if there is no diet reduction.
