new MICU job, pregnancy, and swine flu

(I hate the moniker 'swine flu, but anyway). I was offered a job in a MICU, which I really want to do. I'm also trying to get pregnant with my first baby and have been reading about pandemic flu being more dangerous/fatal in pregnant women. I'm also concerned about taking an experimental vaccine while pregnant. As I see my options, I could
1-assuming I'm not already pregnant, resume birth control, get swine flu vaccine, then stop birth control again
2-stay at my current job at a rehab/long term care facility, where I doubt I have much risk of contracting swine flu, although I know there is still a risk
3-get vaccinated when it's available regardless of pregnancy status/work in MICU
4- don't get vaccine and wear PPE when caring for any patient with any infection (but if a patient with swine flu is on the unit, aren't I still at risk regardless of my own PPE/hygiene)
It's looking like #1 is the safest, it just sucks to go back on the birth control after thinking I might be pregnant by october
What are you all doing about this? What are your thoughts on the vaccine?
