Should I lose weight before i get my belly pierced?

Im 16, 5'6" and 150lbs. im planning on losing some weight and i want my belly pierced for my bdaywhich is next week. will it affect the piercing if i lose weight? i mean i really dont have a lot of fat in my stomach so its not like im cutting 20lbs off it. just a little chubs. so it wont make a difference and the piercing wont migrate if i shed some pounds right? thanks :)
