If I haven't stated my opinion, I am Pro-choice.
The reason is because in the previous period, the fetus is no more than just a collection of organic matter no less living than a brain tumor. I am literally saying that because there is nearly no way that a fetus 1 week old can keep itself living outside the mother after being pulled out, at least practically. You don't feed the fetus something so that they keep on living on its own without the mother or some specialized liquid(and if anything, the wider utilization of this liquid is better than outlawing abortion in all terms).
Unless a fetus can sustain life external of the mother, without the usage of specialized liquid, in Earth's atmosphere, there is no meaningful reason to call it "alive". As a result, aborting a fetus before it can be sustained as such is not even murder. It is as murderous as poking a corpse. Surely you can hook corpses with gas, tubes, wires, etc and they may or may not be able to open their eyes with the littlest amount of consciousness, but it would be again meaningless to declare a corpse alive.
To declare the expunging of something never even reaching the "alive" stage as a murder is simply absurd.
