I removed mine when I was about 8 weeks pregnant. I had it for about 8 years.... they will never completely "heal" so that you don't see the hole, unfortunately...
But- it doesn't stretch at all...it's just a dot that you can see above my belly button! I'll actually probably re-do it after I lose the weight-- and since I can see where the whole was, I can probably do it myself. I never had any problems with infection or anything....but if I did, I'd probably remove it too!!
