Minimum-Maximm weight? For 13 female?

I am a 13 year old female at 5 ft and 3 inches. A couple weeks ago, my doctor said I was overweight. I was always on the line of being overweight or normal, but growing up, you know how that story goes. I always looked kind of fat to myself, but i thought i was being paranoid. So, fallowing the doctor's suggestion, I am going to start to loose weight. But the last thing I want is to be underweight. I was doing some research and want to find the minimum and maximum weight and everything was for adults. So please, can you give me the minimum and maximum weight for MY age?
