I had a belly peircing for almost 2 years ago... Does it have any effect if ever I'm pregnant??

A piercing can stretch out during pregnancy.

I think your supposed to take the ring out when you are pregnant because you can risk an infection. If not they sell those non metal rings you can use.

That's all I know about it.

I had mine done and got pregnant like a year later they made me take them out for like ultrasounds and doc apts at first but when my belly started to grow they told me I should take it out but you can still put the ring in everyday and take it back out that way it didn't close

Use ptfe belly bars.. they're flexible and comfortable so they'll move with your body as your bump grows. I think www.bodyjeweleryshop.com does them but I think this shop has a wider range: http://www.jobananas.com/ptfe-barbell-coloured-acrylic-balls.html good luck
