The basis of needing an abortion is almost always sexual immorality. The Galatians passage aptly covers that. With proper living, abortions would be a non-issue.
Sorry, Paul, who never knew Jesus, may pontificate to his Churches, but Paul never mentioned abortion.
There are many reasons for the need/desire for abortion. Sexual immorality may be one of the many. But not the only. And sexual immorality in the end may produce a wanted child. Thus the reason this scripture is being taken out of context.
