I peirced my belly button a week ago and it seems like it is slowly coming out of my belly button. I don't now what to do and the worst part is Ny mother doesn't now and I don't have any money for antibiotics.but I clean it like 3 times a day. So what should I do?

Tell your mother and get medical attention before the infection spreads.

This could be dangerous - I actually investigatged a case of professional piercing without parental permission, an infection set in, the girl developed gangrene and was hospitalized for an extended period. Why the infection was picked up in her blood stream so quickly I don't know - but she was very, very sick for a fairly substantial period.
