The "pro-life" narrative is largely articulated by the Christian right, and there are important differences between how Judaism and Christianity view the span of time between conception and birth.
Jewish law does not consider the fetus to be a being with a soul until it is born. It does not have personhood. Furthermore, before 40 days, some poskim, or deciders of Jewish law, have a low bar for allowing an abortion.
The Talmud, in Yevamos 69b, cites the view of Rav Hisda that “until forty days from conception the fetus is merely water. It is not yet considered a living being.”
If there is a threat to a woman’s life, the safety of the mother takes precedence over continuing the pregnancy at any stage. Many sources illustrate this graphically and rather unambiguously, and all modern poskim, or religious decisors, agree on this. In fact, in certain circumstances, a fetus that endangers the life of the mother is legally considered a “murderer” in active pursuit.
