I am currently 5 months pregnant (due Nov.10). I had moderate morning sickness in my first trimester that went around week 14. I have been fine since, until yesterday. I suddenly started to feel very ill in town, have felt ill since. Vomited most of yestetday but not so much today. Not sure whether this is pregnancy related or another source (virus, food poisining, etc). Should I see my midwife?
