Is it the stomach virus if i only had diarrhea twice in one day and then once the next?

Possibly: Usually "diarrhea" refers to more than 4-5 watery stools per day. One or two loose stools could be from your diet, medication, stress, or a mild infection. In any case, resting your GI tract with light foods and clear liquids can help resolve the problem most of the time. Avoid milk, fruit juice, and spicy or fatty foods for a few days.
