At 5'7... no. That is the ideal weight for your height, since you are fairly tall.
Plus, you are still so young, and so your body will change over time until you are finished growing in your early 20's or so..
I'm much shorter than you.. I am 5'3, so if I were to be 128 pounds or more, I would be considered overweight, (Plus I have a VERY petite build with not too much muscle.) But since you are much taller than me, you are not fat.
