how does nipple rings work when pregnant?

I got my nipples pierced in September. In November I conceived but didn't find out until December... Has any other ladies gotten their nipples pierced then gotten pregnant 2 months later? What did you have to do about your piercing? Is there some type of retainer you can wear? Women who already has theirs pierced then got pregnant opinions are welcomed also. I'm just curious as to what I should do.
