Aside from the other questions associated with abortion debate (such as religion or privacy rights) this is simply too early to consider something to be alive. At conception, a zygote cannot sustain life on its own. At this point in pregnancy you do not know whether it will become a miscarriage. Are abortions for miscarriages inherently wrong? No, they're simply necessary. Beyond this. There is no reason to refine our understanding of abortion to this extent when we have legal precedent (Roe v. Wade) that says that abortion is legal.
