I'm 21 and 5'8 - I think I stopped growing about years 19-20. I think I was about 5'6 at your age. I think you can still gain a few extra inches the next coupe of years if you try to do some sports (basketball really that's the one that helps) and layoff any heavy weights exercises (they're not good while you're developing anyway).
Healthy lifestyle, sports and a good and balanced diet might give your body a hormone surge and you can still gain in height.
But in order to have clear expectations on what can be when you mature I think you should look at family, relatives and siblings if you have and just accept whatever your genes had given you.
Best of luck and try not to stress yourself too much over it
