Teenager Bmi Table Is A BMI Of 14.9 Okay For A Teenager?

Is a BMI of 14.9 okay for a teenager? - teenager bmi table

I am a girl of 16 years. I've always said I'm too thin, so I wrote my BMI today. Apparently, all less than 18.5 is underweight, the somewhat surprising, but then I thought, maybe because I'm only 16 and perhaps not yet fully developed, but this could be a factor. My BMI is too low?
