Scared and worried

Patient: I am very worried about my pregnancy, this is my second one and at 20 weeks I am very very worried. I have all day vomiting since my first week and a half in, I have no weight gain at all. The baby is moving but has nowhere to move and is attacking my spine (that he is wrapped around) and giving me incredible pain. I went to the er and they told me I had placenta privia but no doctor will take my medicaid
