Belly Piercings.

Hello ladies, I'm a first time momma and I'm 21 weeks. My belly isn't very big yet but I can tell my belly button is starting to stretch a little bit. My first doctor said I could leave it in if I switched it to a bioplast type ring. But my new doctor never mentions it or says anything. When did you all take yours out? Or did you not take it out at all? I need opinions! :)
