first of all, you're more than fine, and secondly, people should already understand what you mean when you say "women" in the context of abortion.

the word "woman" has been used historically and socially to refer to uterus-owners, and we have unfortunately not found a good word to replace it since the word "woman" has now been repurposed for the gender role that those people play in society.

it's a super complex social and language issue that's only recently been actively discussed, and no one is ever to blame for trying to catch up from the social norms they've grown up with.
