Piercing Belly

I've had my belly pierced about 2 months ago the piercer told me if I washed it with an antibacterial soap and blow dryed it everyday it can heal within 2-3 weeks... Problem is every article I researched said navel piercing are impossible to heal so fast.. The piercing doesn't hurt at all but it does have a lil bit of oozing sometimes. What should I do ? Can I change the jewelry?
