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?

It's possible... is there a chance you could be pregnant? By all means, try a test to find out. It could still be a stomach bug hanging around, but if it continues, go back to your doctor as stomach viruses are usually fairly short lived. Either way you'll want to know what is going on.

Yes there is a chance I could be pregnant.. I have been trying for about a year.. today I felt bad all day.. I haven't been eating a lot at all and all I did was sleep today.

There could be, but there is also a virus going around that lasts almost 2 weeks.
