No one suddenly decides that far into a pregnancy that they don’t want to be pregnant anymore. These medical procedures occur because the baby is either dead or not viable and the pregnancy could pose a risk to the mother.
Stop trying to impose your false morality in situations about which you are uneducated and stop trying to control women’s bodies based on your own beliefs (which are misinformed).
Reduce abortions by increasing education, providing adequate health care, and making adequate birth control available. Making them illegal does not stop them, it only forces them underground and makes them more dangerous to everyone.
