A lot of pain, help!!

I was getting out of bed, when a sharp pain hit me on my left side. It got worse when I began to walk. I laid back down on my bed and rocked thinking it would soon subside. The pain gets worse when I move or even breathe. I'm 33w2d, baby is still moving, no gush of fluid, and no blood thus far. Anyone else experience this? Anything that could help? It literally has me in tears.
