Let me give you a scenario to help explain this:
A woman is raped. She is hurt, mentally and physically. 9 months later, she is due for a pregnancy that she has a chance of dying for, a baby born to a man from one of the few men that raped her, and if she keeps the baby, she won't be able to support it and will be forced to give away any educational opportunity.
There are cases when Abortion are the right choice and I narrow them down to endangering the mother's life, rape cases (includes incest), and if the mother cannot support the baby if they plan to keep the baby.
I am pro-choice but I do support the mother allowing the baby to be born but it is their choice, not mine.
