Hi Velvetee, I was lucky throughout my pregnancy and didn't encoutner any bugs until the last two weeks and I had a horrible cough and cold. Sadly, apart from resting as much as possible, and drinking plenty of fluids, which I know you already know, there is not much else you can do - both of those things are not easy to do whilst pregnant and working.
When you get home in the evenings, have a relaxing bath, hot drink and an early night. Up your vitamin C and try to get as much rest as you can xx
