I'm 17 weeks pregnant and experiencing stomach cramps and diahorrea. my temperature is 37.3 which is a bit higher than normal. should i be worried? i did eat some salmon yesterday at an event and i'm worried i might have gotten food poisoning?

Based on what you've described, the stomach cramps and diarrhea could be related to something that you ate or as well to a stomach flu. It would be a good idea to continue to monitor your temperature and try to get through the diarrhea with a BRAT diet (Bananas, Rice, Applesauce, Toast). If your symptoms persist it would be best to see your physician.
