Your friend doesn't need comfort - she went and screwed around without a condom and may have possibly given an std to her boyfriend. Both were aware of the consequences of their actions, so what she needs is to be reprimanded for being a selfish fool, not coddled for helping to spread venereal diseases and possibly making another child to plague the earth.
I say bed, made, lie - whatever bad comes out of her situation, she deserves. You just can't sympathize for people who do stupid things like this.
