According to this site the unborn baby (their words not mine) is considered a zygote for about 7 days (not sure how many seconds that is, but I'm thinking more than 0); at that point the unborn baby (their words not mine) becomes known as a blastocyst.

A zygote is a stage of development in humans from fertilization until it becomes an embryo. A child is a stage of development in humans from childbirth until adulthood. They are distinct and do not overlap. People don't call a child a born zygote, born embryo, or a born fetus because a child isn't any of those things. People call a zygote, embryo, and fetus an unborn child so the can sensationalize abortion. An unborn child isn't a zygote, because it isn't a child until after childbirth approximately 38 weeks later.
