What's happening

I haven't felt my baby move for like two days. I think I feel her but it's so light it could be gas. She was moving a few days ago I could feel her if I put my hand on my stomach. Then i got this terrible pain on my right side on my ribs all the way down my stomach it hurt to touch. My back has also started to hurt. Is this normal? I'm going to the doctor tomorrow but I'm so worried I can't sleep.
