I'm a little over 9 weeks and haven't had any real symptoms until yesterday. Saturday I had shrimp marinated in a really spicy green sauce ( yes I am aware that shrimp isn't recommended during pregnancy but it was a craving). Saturday night my stomach started to hurt, feeling constipated, so I ate a noosa organic yogurt. When I work up yesterday, I felt extremely nauseous and I thought I was dehydrated so I drank Gatorade and sure enough it came back up. Later, I had to run to the bathroom because of loose BM. I couldn't eat anything all day until I had pizza and that seemed to sit well. This AM I don't feel nausea just feel grouchy because I'm tired. So now I'm thinking it was possibly just a case of food poisoning ??
