Pregnant women and the unadjuvanted H1N1 shot in early pregnancy?

I am 5 weeks pregnant. My family doctor thinks I should get the unadjuvanted H1N1 vaccine. Another doctor I've been seeing at the local clinic says I should wait till 20 weeks! I am so confused as to what to do. At this point I am leaning towards getting it just because I am constantly in fear about getting the swine flu (I also have some asthma) and this fear certainly can't be doing the baby any good. I am looking for the opinions of other women in the first trimester and what they have decided to do. Thanks :)
