Pelvic Pain & Pelvic bone popping 😣

I'm 33 weeks pregnant, I've been having pelvic pain for a while already, probably since I've been 20 weeks. When I'm in bed it hurts to move and turn around, even to get up off the couch! ☹️ it's really painful, then while I'm tossing and turning in bed my pelvic bone will pop! 😳 and it doesn't necessarily hurt but feels weird. After it pops its like it's easier for me to move. I'm just curious to know if anyone else has this ?
