vomiting and diarrhea a sign of labor?

Has anyone else had extreme nausea with vomiting and diarrhea but NO fever around the very end of pregnancy that ended in Labor 24-48 hrs later?? Everything I'm reading on the web is telling me my LO is on the way. Lol. Just trying to see how much truth this holds and if any other moms have experienced this. I'm 35w 4d.
