So I had no idea and they did not warn me that a belly button ring would need to be removed for the ultrasound. Luckily I had already replaced my ring with a pregnancy retainer so it was easy to take out while in the office. I needed pliers to get my ring out so I'm very glad I had removed that a few weeks ago. On a side note, my baby was all snuggled up at belly button level so not sure if that made a difference on needing it removed. Just a heads up to those mommies out there with belly button rings that have not done their scans yet.
