Begging for help! SI pain / I can’t walk

I’m on here because I’m literally desperate and can’t get any help. I’m currently 14 weeks pregnant. About 3 weeks ago I started having pain in my lower back/hip area that hasn’t resolved. I’ve had to take time off of work for it and it didn’t help. I literally am walking like a hunchback because I can’t stand up straight..it’s hurts to stand up, it hurts to sit down, it hurts to walk, it hurts for me to do anything. My OB said it’s too early for me to have pregnancy related sciatica pain and he thinks I had something before getting pregnant and referred me to a neurologist for sciatic nerve. I can’t get in with a neurologist and was told to go to my OB. Nobody wants to help me because I’m pregnant. I’ve been doing stretches but they aren’t helping and it literally hurts for me to move. I don’t know what to do other than cry. Somebody please tell me you had a similar story and it got better. I just don’t know what to do…
