Painful Pregnancy

I've tried calling the doctor several times over the past few days but they will not answer and they will not call me back. Without fail I will wake up to rib pain that lasts hours. Hot showers do nothing, ice packs do nothing. Rubbing my side or stretching seems to make it worse and if I try to eat while my side hurts I end up feeling like I'm going to hurl. Everyone I've told so far just keeps throwing in my face that it's normal but won't tell me why or how to fix it. Any suggestions? Any explanations?
