I have the flu. Im pregnant. Let me just say I wouldn't wish this on an enemy. It's even more miserable than when you aren't pregnant, of you can imagibe that! I suggest staying far away and wiping everything down with Clorox disinfectant wipes. Also, if you do get it, drink tons and tons and tons of water. It helps in two ways, one to keep you hydrated which is so important, and two, it flushes the sickness from your body.
My doctor recommends the flu shot during pregnancy. She said her job is to keep me healthy and safe, and I would definitely be worried about catching it. You don't want to have the flu while preggo.
