Any ideas

So lately for the past couple weeks I have been in pain when laying down trying to move from side to side or even my back for a few. Whenever I move I have this sharp pain or maybe pulling in my legs to my hips. There are point where I can’t even move because it hurts so bad. Now I never had this with my son. I’m not sure what could be the cause but any ideas how I can make it feel better at night so I don’t dread going to bed.. also I’m 27 weeks pregnant an I know it won’t get any better but suggestions an ideas would be greatly appreciated..
