I think it all depends of what kind of body type you have. There's 3: mesomorph, ectomorph, and something morp...i can't remember the last one.
Did you start working out for 5 months? You'll get really big in the beginning and depending on the body type you have, lean I assume, you might get really "cut" in another 7+ months or so. You should intensify your workouts and do one specific body part each day.
