Stomach bug with pain/ cramps

Hi everyone today is the fifth day I’m having diarrhea, in the past 5 days I vommitted 3 times. Yesterday is the first day I started with horrible stomach cramps, my OB doesn’t seem to be concerned. Because I’m not throwing up 24/7. When should I be concerned?? I can’t go anywhere because of the risk of going diarrhea.
