You are full-grown: Once the growth plates of your bones have fused it is impossible to grow any more. Generally this occurs 2-3 years after a woman starts menstruating. You need to accept that this is your height. Height is mostly determined by our genes, Diet and lifestyle measures to increase your production of HGH when you were younger may have helped a bit, but it is too late to help now.

Already at adult ht: You are already at your final adult height. Most girls reach adult height by age 14.
