Too sick to work

So yesterday i thought something was wrong with my baby but today i am sure they are fine because i was off yesterday and felt completely fine. So fine i thought i wasn’t pregnant anymore! All my symptoms seemed to have disappeared. But today i went to work and it was awful! I threw up 3 times and i felt so dizzy and really thought i was going to pass out. It was TERRIBLE. So it seems that the only time i fill fine is when I’m resting and when i feel sick is when I’m up moving around too much. Does anyone anything that can help me not be so sick while I’m at work? I really don’t want to have to quit my job again. I’m 6weeks
