Piercing

I seen my OB yesterday and was told that I have to remove my VCH piercing and place a retainer in or just remove it all together. I'm almost 37 weeks and running out of time. Immediately I called the shop where I got my piercing and asked if they had any barbell retainers and how much would it be. I was told he doesn't have any and I would have to order online and then come in. Just when I'm gathering more information so that I can order the retainer myself he says, "I have one. It'll be $10, I'm here all day tomorrow." Just seem kind of skeptical to me. Has anyone else paid $10 just to have a retainer placed in. Retainers are like $2 to $3.49. I really would hate to let my piercing close up. Any advice ladies? Thanks in advance.
