Yes.
Life begins at conception.
While I have never been a med student, I always thought conception was when the sperm and egg joined. Pregnancy was defined to begin at implantation.
FYI I read an interesting article in The Economist last week that says a number of interested groups are moving towards the idea of "life" beginning at the moment of "Quickenning", ie when the mother first beings to feel the babies movements in-utero, and this has precedent in the original Christian view of when life began. Thoughts?
So that would mean that your humanity isn't based on something you are, but on whether your mother is able to feel you? I don't know that any Christian view ever held this. A human being is a human being because G-d made it so, not because another human being declared it so. You may be confusing the issue of when a woman could know she was pregnant before we had hormone-based blood tests. She could believe she was pregnant due to missed periods and morning sickness, but quickening was her proof.
Shalom.
