Pregnancy belly button rings

So before I had posted about the belly button ring I got from bodycandy.com and how it looked and felt weird. Well the other night I gave up on it. I was at work and the bottom charm kept falling off and wouldn't stay screwed on. Also it kept sliding up and down and felt like it was ripping out of my skin! It hurt so bad that I finally just put in a simple surgical steal one with a diamond. I know people who kept there belly button ring in until the day they went into labor and they turned out fine so I guess I will too. I just found it so irritating! If anyone has had better luck with them please let me know!! I also think I'm going to try it again when I'm a little bigger.
