Hi Sillygirl...i know how you feel..same thing here my hubby and some coworkers and their kids have had sv's that lasted 3-5 days also...obviously the viruses are stronger now......but the people that catch these sv's don't think twice about getting sick, like we do, their just not careful as us....and they contract it from their kids or other family members, they share food at work without washing their hands..etc....but you haven't been in any these situations really....i'm sure you'll be fine....please try not to worry too much...remember you need to relax as much as possible when you are pregnant...stress and anxiety is not too good....hang in there..this will all be over soon!
