I have had my period for two years and it is not regular. I am 5'2. Can I still grow taller?

Growth last year? If there was growth last year, probably will grow this year (must check the doctor's growth to know). Most people reach their maximum height in their late teens. Without nutritional problems or chronic childhood illnesses, height is largely based on genetics and parental heights. Aside from eating right, exercising, sleeping well, and being happy, there's not much a person can do to add height.
