Pregnant and terrified

So, I'm unexpectedly pregnant and terrified. I'm broke, a grad student, unmarried, and I don't have anyone to turn to. I used protection (I'm not a dumb teenager or something...)...and I always thought, if I did get pregnant acidentally, I'd just get an abortion. But now, after 2 + months of praying for a miracle and that i'd suddenly get my period and everything would be fine, I don't think I can do it....I don't want to be a welfare mom. But, if i choose adoption, I still need to take care of me for the next 6 or so months. What should I do?:confused:
