help!!!! severe tailbone pain

Michelle
I just want to know if it's normal and what did you do to relieve it? I can hardly sit. I can hardly stand or bend. There's so much pressure and usually I would assume it's the baby but I'm only 15 weeks!!! 
Someone mentioned sciatic nerve but idk if that's it. I just feel like it's pressure from something or my bones shifting. I just want to know if I'm being a big baby about it? When do see a dr about it? It's constant pain. :(
