I also think that you may need to remove it. My belly button has stretched so much that if I had a piercing there, the jewellry wouldn't actually fit.

On the same topic of piercings, I have my clitoral hood pierced, with a bar. I've been wondering the same - whether I'll need to remove it. I didn't think it would get in the way, but I've never given birth before, so I really don't know. It's one thing I've been putting off asking my OB. :-)
