I used a .gov website to calculate your BMI (body mass index) and it put you in the catergory to be at risk of becoming overweight.
However, you're the one who knows your habits best. If you are excerising well and eating well, you are healthy. If you are really concerned about your weight, talk to your doctor or parents. Don't try to handle it on your own.
Also, since you're 13, you're probably still going to get a little taller and your body is going to continue to change, so I'd focus more on excersizing and eating healthy foods to get you on a good track for your future!
