Viruses should not be allowed to affect pregnant women!!

I'm 6 weeks along and just utterly miserable, but not just from the pregnancy. For 3 weeks I've been struggling with a nasty cold that turned into an ear and now sinus infection for the last week. On top of that I've caught some kind of miserable gastroenteritis with severe stomach cramps and diarrhea for 3 days. Around this time in each of my previous 4 pregnancies I've developed Hyperemesis requiring meds and IV therapy to keep me hydrated. I'm nauseated and have no appetite, but have not really vomited yet, so there's that. No viruses for pregnant women, though!! That's just not fair.
