It turns out it was never broken, but that I have a Pilonidol Cyst (which is kind of like a boil, and I think it's sick. If you want to read up on it, do, but I won't make you), and that there was an infection.
As I've looked around the internet, I've seen a lot of stuff where people, when they first have an infection or whatever, they think it's a broken tailbone, so I don't feel too dumb. :) It's good news, kindof. It means that I'll have to have surgery after the baby is born, but it'll feel better in the mean time as long as I can keep it clean and take hot baths every day.
You will all be happy to know, I'm sure, that I woke up this morning and felt no pain at all. I'm sitting on a chair right now that would have killed me before. I am happy, but also grossed out.
