It's always dangerous to try and guess what a liberal means since words have floating definitions in their world, but at a guess, since pandemic means a wide spread epidemic and feminists consider child birth to be a disease, I would guess it refers to any woman who might become pregnant.
But I strongly suspect that these are just two words that this woman thought sounded good together and the combination doesn't have any meaning whatsoever, like the phrase "social justice."
I think you're onto something -- but even at that, it won't parse. Of course, dealing with people who are flummoxed by "is" . . .
