I have had vomiting and diahorrea (spelling?) for one and a half weeks, feel very worn out as 20 weeks pg and have two year old to keep on the straight and narrow. Phoned doc today who is not in the slightet concerned, told me just to have light diet and if still same in a few days go see her. she is normally very good but I'm still worried, how long do I let this continue? Any suggestions what I can take to stop this?
