For me, once implantation takes place, I do not believe in aborting any of the fetus. Planting too many in the hopes of being able to abort some is the deliberate killing of an unborn child...many disagree with me and many think the same way I do....the only position for a legit abortion is a tubal pregnancy which can kill the mother and the zygote has no change to implant and form a pregnancy..The tube will rupture when the zygote gets large enough to blow out...both die...
You wish to think that no extras were produced. I guess this salves your conscience but it is not fact. Natural pregnancy is very hit or miss; artificial methods also. What pro-abortionists accuse God of, science is certainly guilty , which is to waste many lives in the interest of saving one.
