First of all I want to know if it is safe to get your belly button ring changed or even pierced when you are pregnant? My wife already has a piercing luckily, she does not have to get one done, but she wants to change it. Every time I see the stomach I just feel it would burst. I have never really understood this pregnancy method. How the stomach could stretch so much? Anyways, she wants to know if she could change her belly button? What are the online sites that are good enough to buy the pregnancy belly button rings?
