Tailbone pain

Does anybody else have pain in their tailbone? I don't know how to describe it but the last few weeks of I'm laying down there's a pretty intense pain in my tailbone. Sometimes it's like a sharp pain if I move my legs or sit up weird. I've read that it's because of the pregnancy and because the muscles on my pelvic floor are changing? But I just want relief! I feel like if I could pop it it would feel better but I don't know how to pop that far down on my spine! Does anyone else have the same issue or any tips on how to fix it?
