Hello, im pregnant 7 week today , but my stomach always hurt, is it very seriously? thank you

Many possibilities: A simple tummy ache with symptoms like nausea, vomiting, or diarrhea, whether at home or traveling, may be from a virus infection, bacteria infection, or contaminated food. A normal person, whether pregnant or not, usually recovers easily. However, certain bacteria are damaging to baby fetuses, so be sure to avoid undercooked foods. A doctor can check for other pain causes, like acid disease, etc.
