When you reach a certain fat percentage, you will start menstruating. I don't remember the exact percentage, but I think it's something around 13%, or more. I had a friend who was into track and long distance running early in life and didn't start menstruating until she was 18. She had no fertility problems later. It wouldn't hurt to talk to your doctor about it though, just for your own peace of mind.
Is it normal that I don't have my period and I am 16?
