I am 23 wks pg, and had bad diarrhea last night and a cough has come on. no fever, and I am prone to bad stomachs in pg, and being sick or having diarrhea in the night isnt uncommon for me. however dh is panicking and wants me to call doctors to get prescription, but i dont want to be prescribed anything unnecessarily. I am v tired, but that could be because i was up in the night with stomach (which is OK now) and dd. Any thoughts? I'd really appreciate some sane advice.
