Tailbone Pain

Is anyone experiencing tailbone pain? It literally feels like I have a bruised tailbone. I read it could be the babies position since it is so close to my spine or sciatic nerve pain. Hurts to sit, move from sitting to standing or worse laying down to standing.  I called the obgyn office, a nurse called me back n they said it's a little early for me to be experiencing this being 16weeks 5 days and to follow up with my primary care physician. I see my ob on Tuesday so idk if I should follow up with my primary or wait til I actually hear what the doctor has to say. Curious on if anyone else is experiencing this or has ever experienced this in a past pregnancy.
