Hi S.,
I know you've heard a lot of differing advice and I doubt that I have much to add to the discussion - but I'm throwing my two-cents in anyhow...
I'm also a school teacher (who never gets the flu shot), I have a two week old baby and a toddler in daycare, my husband works in health care...so I've been struggling with the same questions. My thoughts are just my opinions, but hopefully they are helpful.
I wouldn't get the H1N1 vaccine because it won't have been well tested. H1N1 is the flu, a little more contagious and with a stronger impact on the young, but for most people it is just the flu. Pregnant women aren't more succeptible to it, but they may have worse outcomes because it can be harder to maintain adequate hydration and because pregnancy makes your body a little unpredictable. If you practice serious handwashing and use hand sanitizer you really should be okay. My husband worked in a clinic treating multiple cases of H1N1 throughout the last 3 months of my pregnancy and no one in my family got sick.
As far as the regular flu shot goes, that is a little less clear. The argument is that people should take it so that they don't weaken their immune system by getting sick with the regular flu and therefore become more succeptible to H1N1. Handwashing still works better than anything. If you do get the regular flu shot make sure that it is the version that is safe for pregnant women and babies.
Good luck! Most importantly, try to get lots of sleep, stay hydrated, and wash your hands!
