It might be worth a call to your doctor.. sometimes diarrhea and irritated bowels can cause people to go into labor, contractions, etc.... One of the reasons why spicy food and castor oil are said to work... they say it wont do anything if your body is not ready but with your preterm labor issues, you never know when yo ucould be ready..
i would also file a complaint with the restaurant because obviously it is something going on there if all 3 of you got sick.. im not sure where they would go.. but you could see if you could get a refund at least.
I did end up calling my doctor and he said if i continue feeling like poop for another hour then I should go in the L&D to be monitiored bc of my preterm labor issues and to make sure I'm getting enough liquids. So i'm going to wait until my husband gets home for lunch and then take it from there. And i am calling the place and I want my money back we payed 75$ for three people to eat not to get very sick.
This is my main fear, is food poisoning. People think I am crazy cause I am very picky with my food and where I eat. My hubby, doesn't know much about hygiene and I am always on his back about food preparation, but all it takes is one case of Lysteria bacteria to cause trouble to your baby.
