If i weigh 121 and am 14 and am 5'2 am i over weight?

well it depends is it mostly fat or mostly muscle? Muscle weighs more than fat. A normal weight for a person 5 2 is 110 pounds. The way I know this is that once you reach 5'0" you should be 100 pouds. for every inch after that you are allowed 5 moure pounds! Hope I helped
