You should go see your pediatrician
or your adolescent doctor
as soon as possible.
There is a great deal of variation in how people progress through puberty, and for some people this may occur later than in others. However, you have raised multiple concerns, such as little pubic hair, little change in voice, and short height. All of these things may be related to trouble progressing through puberty, and so the first step would be to have an examination with your doctor. They can look at various characteristics, such as distribution of body hair, size of the testicles and penis, etc and help determine whether or not you are progressing. They can also ask some questions about your family, such as the height of your parents, to see if your height it appropriate or if there are any other clues that might uncover a problem.
Based on what they find, they may want to perform some basic blood tests look at hormone levels in the blood. They may also decide to refer you to see an endocrinology specialist
if there are any concerning findings on the blood work or on the physical examination. Contact your doctor as soon as you can!
