You don't sound fat to me. I'm 4'11 and I weigh 134lbs. You're a little bit taller than me. I'm not considered fat and I have my belly button pierced.
But it shouldn't matter anyway. Stop being controlled by other people's opinions. Just love yourself and do what makes you happy, fuck what others think because it's just that, their thoughts. Your opinion of yourself is much more important than what others have to say about you. Good Luck and be happy :)
