Pain in my butt!

Anyone else having pain in butt muscles... well not really butt muscles... it's at the top of my butt close to my tailbone?   Hurts sooo bad to walk.  ?  Pregnant 9+3
Is this a pregger problem?  Will it go away?
(I don't want to tell Dr. if I can get away with it cuz they'll insist on imaging and drugs.)
