I got my belly button pierced on 6/1/09 and it was hard for the guy to do it because I have already had it done once and I had a lot of scar tissue. The first time he pierced it way to high in fact there is about a half inch between my scar from the last piercing and the new one. Anyway what I was wondering was what is the soonest I can change my belly ring after getting done. It's been one day and already I'm wanting to change it. It's looking a lot better than it did the first time and not nearly looking as infected. Any way how much longer do I have to wait can I take it out by 7/12/09

I would check up on really being able to take it out on 7/12. When I got mine done I was told that it took six months to truly fully heal. If I were you I would just be patient, clean it as you were instructed to and hold off on changing it for the time being.
And what do you mean its not nearly looking as infected? As infected implies that it is already looking infected. That's bad if that's what you're implying.

Well I have had it done before and it got really infected and gross

OK. That's in the past though... I can't possibly help you (nor can anyone else) if you don't explain what's going on now. Is it looking like its getting infected again?
