Multiple episodes of vommitting! Please help!!

I just had my appointment today and am 7w. I've had some nausea here and there but this evening got really bad. I have a bad headache and have thrown up 5x in the last 4 hours. Can't keep any food down and am just dry heaving at this point. Has anyone else experienced this? There had also been a stomach virus going around at work so not sure if I caught it or just bad morning (evening) sickness.
