I have to say that I agree with all the previous posters. Please don't go unless you can offer some support to the girl.
However, fwiw, I can say that when I was a teen, there were several pg teens around. Seeing them didn't make me want to have a baby too--instead, it brought a good dose of reality, more like "holy crap. . . this COULD happen to me". I wasn't a virgin throughout high school, but seeing those girls made me double check my protection methods and think twice about what if. . .
