Morning sickness or stomach bug?

Yesterday at work I was nauseous and dizzy all day long. I never got sick at work but I was constantly drinking ginger ale or eating saltines. I get home, lay down on my left side, and suddenly have to throw up. After that I couldn’t stop getting sick for the rest of the night. I took the day off work and felt like such a wimp for doing that! But I wondered if I was having severe morning sickness or a stomach bug?! I also got kind of worried about the baby.. I’m only 9 weeks pregnant and I was thinking that I’m getting rid of any nutrients for the baby!
