That's about right for your height.
according to the body mass index calculator you are actually underweight. check it out for yourself. (the first one is the calculator, the second charts to compare yourself to the average.)
Your ideal weight at 5'9 would be 145 lbs so 128 lbs is OK.
As you get older you will thicken out automatically.
