Is there still I chance I can grow?

I recently turned 18 and I am 5'7. I work out regularly (mostly weight lifting). My dad is 5'11 and my mom is 5'3. I've been eating healthy and doing stretching exercises in the morning and night (inversion table as well) I take l-lysine and l-arginine 3 times a week to boost my hgh production. Should i continue doing all this and is there any way to see if ive stopped growing?
