My husband has a slight fever 100.5*f and achy joints. I woke up this morning with a pretty decent sore throat. Normally at the first signs of getting sick I would load up on zinc, vitamin c, elderberry syrup and echinacea but I am currently 6w3d pregnant and am unsure if those are safe? Any suggestions to stop this cold in its' tracks??? PS we're leaving for vacation in less than a week and I REALLY don't want to be sick for that!!!!
