It's quite possible that you will still grow taller. Menstrual cycles can start at a wide range of ages, and most girls continue to grow for a few years after their first period. Generally, girls tend to grow in height until about ages 16 to 18, though this can vary individually.
Genetics also play a significant role in determining your final height. If your parents are taller, there's a good chance you may continue to grow as well. If you're concerned about your growth or development, it may be helpful to discuss it with a healthcare provider who can give you personalized advice.
