I'll chime in with the earlier comment about pregnancy.

I'm a midwife, in practice for 14 years. Over the past 8 years or so, I've seen lots of pregnant bellies with a scar like this: ( then the belly button, and another scar, like this: ) The scars are sometimes an inch apart. I'm not sure, cuz I don't ask, at what point the women had to take out the piercing. But it's clearly much bigger than when they started!

I'm in the "better a piercing than a tatoo" camp. My right ear has three holes in it, from back in the 80s (only one hole in the left ear). Now I wish I didn't have those two extra holes, but they're not all that noticeable. I definitely don't want art on my body that I can't change! But that's me...

Keep us posted!
