Hello girls! I think I have food poisoning. Diarrhea and vomiting since yesterday, 9 times in 12 hours yesterday. We called an ambulance, they didn't give anything, they were afraid because it's already 39-40 weeks pregnant, maybe the baby will appear soon. I gave charcoal but I drank only by weight, 80kg. I took 4 tablets, and I also drank rice water, only one glass, refused to go to the hospital. Today for 6 hours, 5 times, I need a system, but with pressure good, temp and nausea are not there, the baby is moving... who had this? How did you treat it?
