Is it infected?

Andreece

I’ve had my belly button piercing for almost 7 months now and just recently I got this red almost like pimple on it. Last night when I was taking a shower I saw there was puss inside of it so I thought it was a pimple and tried to pop it. It wasn’t. The puss came out of the piercing and it started to bleed. Could it be infected? I just changed my piercing from a dangling one to a regular one hoping it would help.

Help please
