I have a belly button piercing but since i found out i am pregnant, i've taken it out and put a retainer in. When i purchased it, i thought it was ganna be like a flexible silicon kind but its actually plastic. i am 22 weeks pregnant now and i've been thinking about taking it out because i am afraid of it closing up. I've had it for a little over a year already. and it looks just fine and doesnt irritate me at all. What should I do?
