I have been sick since before Christmas. went away for two days and now is back with constant vomiting and diarrhea. my cervix is soft and dilated. I don't think my little man is going to stay in till Feb 8th. my Dr said to not take anything at all by mouth for 4 hours then clear liquids only until I stop getting sick. then bland foods for several days.
