Wrong. The intent is to prevent pregnancy. Zygotes will fail to implant for LOTS of reasons. One in five pregnancies end in miscarriage.
I just don't believe it's human life until it is a fetus.
I'm pro-life, but I'll allow the morning after pill for rape victims. I'd not sold on it in general though.
I believe pregnancy = implantation.
I am against all surgical abortions, except in an immediate life or death situation.
