I got my belly pierced 3weeks ago and the person who pierced it said to come back in a month-6 weeks and that they will change the belly ring for me. Well I'm wondering after they change the belly ring how long I have to wait until I can change it again?

After about 6 weeks you can change the piercing as much as you like, but be careful when doing so. The piercer offers to change it for you as a courtesy, you don't have to have him do it, but I would recommend letting him do it so you know what to do when you want to change it yourself. :)

OK thanks... and after he changes it do I still have to clean it or does it mean that its already healed?

Even completely healed piercings should be cleaned to fight off bacteria. At 6 weeks the piercing is still fresh, so I would recommend still cleaning it at least once a day (when you shower is the easiest) with anti bacterial soap. When the piercing gets a little older, about a year old, you can get away with cleaning it 3 or 4 times a week, but its still best to clean it everyday, even then :)
