Opinions on abortion? Pro-choice and pro-life please.?

Ok, from my standpoint I am on the fence. There are times when an abortion is necessary, and some when not. I believe there should be a limit on how many a woman can have. If their addicted to drugs/ alcohol, and choose to abort their child, they should be immediately steralized. I personally have had 1 abortion in my life... I was raped by my older brother for 4 years and concieved at age 11, told my parents about the rape when i was 20 weeks pregnant and immediately had the abortion the next week. It was the most horiffying experience i have ever been through. I grieve about it every day. On the other side, most women who have had abortions know they have done something wrong... They grieve and are very hurt, so why ***** at them more? I just dont know anymore... I'm looking for some views and/or personal experiences? Have you known someone who has had an abortion, and how do they act/ feel afterward?
