Painful tail bone before labour?

I’m 37 weeks pregnant and experiencing really intense pain on my tail bone area. It genuinely feels like a broken bone and hurts when I move a certain way, sit a certain way or touch that area at all. The pain is very intense especially when moving 😢 I recently read this can happen in the build up to labour due to baby’s position and the hormone relaxin being released. I’ve had mild irregular pains in my tummy too. Wondering if you have experienced this and if so how soon after it started did you go into labour, TIA ☺️
