Need Help With Financial Questions on FAFSA!!?

I wasn't married in 2007, but now I am so I said that I am married. I did not file taxes last year,(I made very little money) but my husband did. For questions 36 and 37(income tax and exemptions) do I just put his income tac and exemptions? Also, how do I figure these things out? I have a copy of his W2 but we cant find his 1040. Also, I am pregnant and will deliver in June, can I count this as a dependent?
