Belly button ring and pregancy?

I'm 34 weeks pregnant and looking at mine right now - I'm 17. The hole itself is most likely closed, haven't tried fitting anything in there, but you CAN purchase pregnancy belly button rings that are plastic and stretch rather than metal. It was doing good until about three weeks ago. I have ZERO stretch marks anywhere on my body except right inbetween my belly button and the piercing hole for some reason. Two lines going crooked.... Would probably be different with everyone.
