Many of those women did not “see” it happen like the woman in this story. Women having an abortion are often sedated. Even if they are not I promise you the clinic never lets them see the body parts even when they ask too.
I read about one clinic that did and it was a bad mistake for them so after that they just put some blood and afterbirth in a dish and showed it to women who asked to see it.
Oh. Makes sense; regrettably.
