gauged belly piercing?

​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​i got my belly button pierced about two years ago and it used to be a small hole that the skin would wrap around the ring. now it's like i got it gauged. i've tried to take it out to see if maybe it would close up a little bit but i didn't see much of a difference. any suggestions or ideas of what happened? i used the same gauge ring ever since i got it
