Why won't my belly button heal? it's been 9 months

I got my belly button pierced on May 5th, 2012 I've been told it takes 8 months to a year for this piercing to heal. I've taken very good care of it, never touch it, always clean it but it's still disgusting, it bleeds all the time, there's yellow pus on the top and bottom, every morning I wake up the whole bottom ball is covered in crust.. its disgusting. I'm tired of it at this point and want to take it out but I don't want it to close and there be an infestation closed inside, I don't understand, I use sea salt spray on it. Why won't it heal?!?
