It entirely rests on your personal opinion of embryo/fetus and its status as a living, "ensouled" human. (I use "soul" because there is a distinct difference between a non-thinking human and a thinking human; "soul" is an easy word for that difference.) In this case, you do not even need to create a fetus; once stem cells are generated, you can clone an almost infinite number of them without growing the embryo any further. Therefore, the question is whether life begins at conception or not, and that's not for me to decide.
I will throw out the Jewish belief, that the child is not "ensouled" until birth (by whatever method) and that if the mother's life is in danger, the mother always comes first; in those cases, abortion is mandated by law to save the mother. This isn't to say the fetus is not important, but if you are looking at it from a religious perspective, it might be worthwhile to research various beliefs and decide how they fit in with your personal moral system.
