It depends on your body. Some people stay open and just shrink. Other people's navel could close completely in a matter of minutes.
It depends how long you've had it and how far along it is in the healing process. If you take it out while it is still new and unhealed, it will close very, very quickly.The longer you have had it in, the longer the hole will stay open if you take it out.

As long as you have a belly button you can get your belly pierced. Remember that you're doing it for you and not anyone else or their opinions.

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.

If your belly button ring has a blackish scab you may have torn it or pulled it a little on your clothing. As long as there is not discharge or redness, it isn't infected.
