Is vomiting and diarrhea normal in early Pregnancy?
I had diarrhea for two weeks when I was 8 to 10 weeks pregnant (normally once or twice per day). It seemed as if it was in place of vomitting. If your wife is running a fever she needs to see a dr. and probably means she has a bug. If she has no fever the diarrhea will eventually run its course. The important thing is that immediately after she has diarrhea or vomits she should drink 1 cup of Pedialyte or at least a Gatorade to keep her hydrated. If the diarrhea is severe she should schedule a dr. visit as well.
