Pubic Bone Soreness - 25WKS

My pubic bone has been so sore the last week or so. It hurts to change positions while sleeping (literally wakes me from a dead sleep), It hurts to walk, it hurts to stand up from a sitting down... I know Relaxin is pumping but does it cause pain like this!? Im 25 weeks pregnant with my 4th baby and i don't remember ever being this sore. 😳 Could something else be going on? and no, its not sexually caused for sure because sex is apparently a sin during pregnancy according to my SO. smh.
