The last 2 days.. every morning I have got up with nausea and the first day vomiting. Both days Diarrhea. So I just went to the doctor and they said it was the stomach virius so I got to feeling better and went back to work and the next day I felt nausea again plus diarrhea. And at work when I ate I got sick to my stomach again and I have to take the medicine the doctor gave me for nausea and vomiting. But at the doctors office they didn't check to see if I was pregnant. I have read on a few sites that diarrhea could be a early sign. Is this true?
