I did a project on the long term effects of abortion once. Something like half of all women develop PTS or something like that as a result of their abortion. I can't really remember. I just remember reading the study results and seeing that 5% of the women polled believed, 10 years later, that God hated them for what they'd done, or the 3% polled that had regular, recurring dreams of the baby.... 10 years later.
It was something to do with the fact that during pregnancy you have all those lovely hormones chemically programming your instincts to "Protect Baby", so killing the baby through an abortion, especially 2,3 trimester tends to be actually traumatic....
And that said, why would anyone be stupid enough to have sex without expecting a child?

Accept the consequences of your actions, you can have an abortion if you want, but I'm going to think your pretty much an irresponsible fool for getting pregnant in the first place. Its called birth control. Condoms and the Pill. And even then, its rather stupid to engage in reproduction without expecting that it might actually work....
