Help! ???

I went Black Friday shopping all night & started to feel blah around 4:30am. I've been nauseous this pregnancy but have never thrown up. I have thrown up 6 times and can't keep anything down including water. I called my doctor and they said if I feel dehydrated to go to the hospital that it sounds more like a bug than morning sickness. I'm miserable, really shakey from being tired, my stomach is totally empty so it feels horrible. I don't know if I should go up to the hospital for an IV and meds or just go to a walk in clinic to see what they say. Id hate to go to the clinic and them send me to the hospital anyway. I'm 10 weeks 5 days and this is my first time being very sick. What would you do if you were me?
