No, that's not my argument at all. I fully understand that some women are raped. Lots of things happen to us in life that are not our will and leave us without a choice. "Once a woman develops breast cancer, she is either a cancer victim or a cancer survivor; she has no other choice" -- that statement doesn't require her consent to the cancer.
My point is that once a baby is conceived, there is no reversing the fact that the baby exists. The parents are parents, regardless of whether they want to be or not. If they opt for the fate of their child to be death, then they are parents of a dead child. They can't reverse the fact that they are parents.
Every pregnant woman already has a baby. Some babies die in utero. All babies die at a young age. All people die eventually. That doesn't negate the fact that they were ever alive!
We don't -- or shouldn't -- determine whether someone lives or dies based on what we believe their destiny might be.
That being said, I don't only focus and sympathize with the baby, even though he or she is 100% defenseless and a victim; I am also fully sympathetic with the mother. I recognize her plight and believe in supporting her emotionally, physically, and financially. Women deserve better than being told they can, should, or must kill their babies to lead full lives. Causing others' deaths never advances our lives in any meaningful or positive way.
