my best friend was advised by her doctor to seek out a "pregnancy safe" belly button ring. she got it from the local peircing place. it's a very tiny hoop just to keep the hole. if you ask your local peircer about it, he would probably be able to recommend something to you. how long has yours been peirced? i've had mine in for 12 years and go several months at a time with nothing in it and i can always get the ring back in.
