I did it on a .gov website and it said this;

Based on the height and weight entered, the BMI is 12.9, placing the BMI-for-age below the 1st percentile for girls aged (Age edited out, you don't need to know how old I am). This child is underweight and should be seen by a healthcare provider for further assessment to determine possible causes of underweight.
Answer:
12.9 is dangerously low, malnutrition has got to be an issue here, not to mention other life threatening potential complications. It is very bad, and you need medical treatment.

I assume you're 12-16, you're growing up withouit growing out, this is normal. be thankful you're not on the other end of the spectrum.

A BMI of 12.9 is underweight. It's not necessarily "bad" in itself, but you should be aware that being underweight is not healthy. It is as unhealthy as being dramatically overweight. To properly evaluate your health status, it might help to know your age or the age of the "child". If you are still "growing" the BMI may not be as accurate as if you have reached adulthood.
