Moms with piercings!

I have a few questions! First of all all you mommies to be or mommies out there would you recommend taking out my bellying? Or just putting the maternity one in? And if so when would be a good time? Next question when in labour will I be asked to take my piercings out? Cause I have a few that I really don't want to take out in risk they grow in and don't feel like getting them re-pierced! (Hurt enough the first time!) thanks! :)
