I'm the dash of cold water on this one. Frankly grow a pair. You SHOULD have insisted that you were going to wear a condom; that was your CHOICE not to; yours alone to make so don't expect a pity party here.
As for the BCP I have a 13 year old daughter whom I concieved while taking birth control pills.
Birth control pills are not 100% effective, have never made that claim and frankly I think you are being entirely selfish, going out of your way to make this girl miserable because this pregnancy messes with 'your' life.
Well bucky guess what? IT MESSES WITH HERS TOO!!

You are not and will not be the only person involved. How DARE you think otherwise? Will you gestate for 9 months? Will you endure labor? Will you have an abortion? Will you have to hand over the baby you just spend 1 -3 days laboring to birth into the hands of a stranger? You may go onto school; she will have to find and pay for daycare in order to work or get educated or both; you will face a penalty of something around an average of about $200 per month; Where the hell did you get the bright Idea a girl can raise a child as a single mother for $200 per month?
You are angry? You are hurt? I think that she is better off without you!!
Get a grip.
You are thinking only of yourself and Future I really get a kick out of your sudden turn to villifying the girl; how convenient we haven't seen her side of things.
Pagh..grow up. Both.

*Edit* I am not going to play your little voting game because It is NOT your choice
