I'm 12 and I need help growing taller!?

I'm 12 and I haven't grown tall for four years. My mom is 5'0 and my dad is 5'2. My parents and I are FiIipinos (asians), including my sister. I do play sports like kickboxing and basketball. In addition my sister is even taller than me like around 5'3 and she's only 11. I eat right and exercise everday, but she doesn't. I'm 4'9 and people still make fun of me because of my height, and to this very day i try to grow at least 4 inches taller than my dad. I do drink milk and eat fruits and vegetables. So is there anyway that i can still grow taller before the age of 14 without any medications or pills? If so, please do tell or Comment.
