Extreme pelvic pain at 28 weeks

I've been having extreme pelvic pain for the past three to four days. I can barely walk, it hurts to sit in a chair or lay in bed. Anytime I try to put on pants or shoes, I get tears in my eyes because it's hurts so badly. The pain is at the top of my inner thighs and pelvic wall. It honestly feels like the baby could just pop out. I went to the doctor today and he just brushed it off as though it was normal- he did say I was experiencing it "earlier than normal." Is anyone else having these symptoms or have any solutions that can help this extreme pain? I'm miserable and don't know what I can do.
