Tailbone Pain

Allie
Is anyone else experiencing excessive pain around their tailbone? I know that tendons and everything in my pelvic area are stretching a lot, but at the end of most days I have trouble walking and changing body positions. I won't be surprised if I feel like this when I'm in the third trimester, but I'm only 9 weeks along right now. The pain is present when I'm sitting, lying down, or moving around. It's intense enough that I cry out if I stand up too quickly. I didn't fall or fracture it. 
Tylenol is completely ineffective for any kind of pain for me. I've tried stretching, prenatal yoga poses, and even using a foam roller. Nothing gives me relief for more than a few minutes. If anyone has any advice or ideas, please let me know!
