Honestly over this pregnancy

So I'll be 37 weeks tomorrow and the last 4 weeks have been awful. I have damage in my hips, back and pelvis from a previous car accident. I'm in pain constantly. I can't sleep and walking is such a battle. I have an almost 3 year old too. Any thoughts on getting g through these last few weeks??? I am to the point where I'm crying daily from the pain. I've done the chiro, yoga, and stretching and none has helped. advice please!
