Morning sickness?

I'm 9 weeks and 2 days pregnant. I'm usually okay in the mornings when I come into work. But this morning I was more nauseous than usual. About an hour into my shift I started throwing up, and then I was getting hot flashes and sweating. In afraid to take my prenatals in case I throw them up too because I can not keep food down. Anybody else have similar symptoms? Should I be worried?
