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.

It depends on how long you have had the ring. I got my belly button peirced when I was in high school but my coach let me tape it down and by the time competitions came around it was healed enough to be out for a few hours... if it has been over 6 months I would imagine you are fine.
3 to 6mths..it also depends how your belly button react
Your body had healed around the ring to such an extent that it will take a long time to, if ever, close. Besides accepting the fact that your body peircing is at least semi-perminent and putting another ring in the existing hole, there is nothing you can do to speed healing.
