When you get pregnant, most care providers recommend removing your belly button ring. Even women who don't remove their rings report that belly button rings itch and pull as the belly stretches around the fifth or sixth month. There is also the risk of infection if the belly button ring scratches you or opens a small wound. If you do take out your belly button ring, the piercing hole will probably close, requiring you to re-pierce your belly button after having your baby. However, if you don't want to take out your belly button ring you may want to purchase a non-metal pregnancy piercing ring. These are flexible and two inches long to accommodate your growing belly. Pregnant women claim that this product allows them to keep their bellies pierced without the discomfort of other belly button piercing.
