Morning sickness ?

I can't keep anything down at all. My birthday was yesterday and it had to be the worst day of my life. I haven't eaten a meal since then. I can't keep down water , gaterade or cranberry juice. I've tried ginger tea , the sea bands acupuncture bands still nothing. Ginger drops everything. Should I go to the emergency room or is this normal ? I'm 8 weeks today. This is my first pregnancy.
