Well, newb, 'round these parts, we properly call "keeps her fetus"...
GIVING BIRTH TO HER BABY.
And the opposite case would be killing her baby.
In this context, referring to the human being inside the womb as "her fetus" is very dehumanizing. That human has the right not to get sliced up into ribbons.
Thank You, I love how you said that. A red flag goes up when I hear people referring to a fetus
