Hi i went through a full pregnancy with a maternity belly bar in my navel, i did have to make sure it was clean more than normal other than that it was fine.

this is my second pregnancy with my navel pierced and i have no intention of removing it. i was so surprised that i was able to keep my navel bar in that i decided to sell these bars mys elf as i had lots of good stuff to report on them hope this helps.
