With puberty, nothing is set. There are changes all the time and whether you go through it slowe than others, let it flow naturally. It is usually genetic and to simply put hormones in can cause side effects to the way your body naturally runs. They do check your height which is part of a puberty analysis. If you feel something is really wrong contact a professional or doctor. In the mean time, be patient with your body. Good luck!
