Ok i got my belly button pierced and i've had it done for 4 months now and the piercer told me that i could change it in 3 months but everyone else says they waited 6 months to a year?? i don't want it to get infected and i don't know if it would be a good idea to change it. what are some signs that its healed and its safe? And can you give me some tips or advice please? all answers are appreciated!! thanks.
