I support a woman's right to choose whether or not to carry a fetus to term. 
In valuing life, I admit that I value my own. To me, life is about making my own choices, the ability to engage in activities, the freedom of being an independent person. I do not think that I would want to have been born with fetal alcohol syndrome or meth addicted and affected, I would not wish the hell of my prostitute-mother's current boyfriend raping me, or getting locked in a closet or chained in a basement - enduring torture for months on end. 
Not every pregnancy is a happy event. Life is hard enough under the most basic circumstances. Having abortion as an option can be in the best interest of mother and child - I MO. That said, any means of birth control would be my first choice - the pill, patch, shot, condom, abstinence - and unfortunately, the responsibility for that is on the woman. It would be different if men got pregnant, guaranteed.
