Severe Symphysis pubic disfunction

Anyone ever dealt with this. I was fine before my car accident never felt any pain but now it feels like my pubic is splitting in half when I walk by a bowling ball. The hospital dismissed me since they monitored baby and his heart rate was fine Nd my pelvic was not broken but me on the other hand is on a wheelchair and freaking walker because the pain is that severe it feels like baby is falling out, my stomach looks lower like he’s dropped but sadly my next ob appointment is Thursday, I called to let them know but can only talk to receptionist they said they will talk to her tomorrow to order an ultrasound or see what she’s going to do. I can’t walk is there anyway I can relieve the pain , I tried Tylenol extra strength and a pregnancy belt, trying to wobble around to walk, stretching my hips in butterfly position, Ice pack, Nd even a video on how to pop it but it won’t pop and still no relief, if I can’t walk by Thursday morning then there is no way I’m making it to that appointment cause I’m not about to walk up in there literally WOBBLING trying to keep my legs even against gravity. I just wanna be able to walk again I’m not due until July 26 I seriously can’t wait that long. I can’t roll over in bed without feeling the pain even when I’m sleeping I can feel the pain. Is there any kind of relief for this it’s sooooo much pressure I want to scream when I walk
