Women have always been at the mercy of men when it comes to child bearing and child rearing. That means there have always been approved ways of not having one, ways that were subtly encouraged by other women and thus supported historically even when illegal. Even the murder of just born infants was not really taken seriously at times in our history.
While abortions have been around since the beginning of time using all sorts of different methods and techniques, no major culture no matter how primitive supported abortion. While some societies like Ancient Rome or Ancient China might have accepted it more than others, it was never made legal and always frowned upon by even the ancient societies with some of them even punishing abortion with the death penalty.
