Best Answer: If you want to change the ring. You go to the PIERCING OR TATTOO PLACE YOU GOT IT DONE AT. 2 and 3 weeks are to early to do it by yourself. You usually wait 6 months to change it by yourself. You have to wait for the scar tissue to heal, if you don't there is a big chance that your belly skin will deny the new ring meaning it will get infected. It happen to my friend. The piercing place will probably just charge 10 or 20 dollars. But it's worth it.
