Around 2 hours after dinner last night my 13 year old complained of stomach pain. At 12 midnight she began vomiting. At that same time my 18 year old began complaining of stomach pain and nausea. At around 4Am she bagan vomiting. At around 5 am, I 40 year old mom, began feeling stomach pain and awful cramping. I also felt nausea and at 12 pm today began with diarrhea. Next, my 21 year old came home sick from work because of stomach pain vomiting and diarrhea. I'm not sure if it's something we ate, or a bug going around. My husband and youngest daughter are perfectly fine. We all had the same thing for dinner together last night! so confused. not sure if we should go to urgent care, or wait it out...
