 What about the bodily autonomy argument for abortion?

A third trimester baby can survive outside the womb with medical help nowadays, so aborting it could be considered wrong for that reason, but assume a time period or situation where this isn't the case. The bodily autonomy argument would mean that a (hypothetical) 9th month abortion is okay in the above situation.

This involves killing an intelligent human, and as mentioned before, almost no one would morally agree with this, except in situations where the mother’s life is at risk. And an argument which leads to a disagreeable conclusion, is itself disagreeable. So this argument for abortion isn't very good, but that doesn't mean other arguments for it aren't.
