I am almost 16 and a half years old and i am a male.  I am 6 foot and a half inch at night and fear that i have stopped growing. my doctor said i would be around 6'3 and so do all the height calculators online. i havent rlly grown in like 6 minths and fear that i have stopped even though the doctors and everyone said i would be taller. is there any way i can have another growth spurt after this slow growth period?​
