Twins in-utero, and Abby Johnson's observations

Unborn twins interact with each other as early as 14 weeks: (Edited for prochoice sensitivities) '“Starting from the 14th week of gestation twin masses of pregnancy tissue plan and execute movements specifically aimed at the co-twin,” the authors wrote, stating that “when the context enables it, as in the case of twin masses of pregnancy tissue, other-directed actions are not only possible but predominant over self-directed actions.” The findings provided quantitative empirical evidence that masses of pregnancy tissue are very much aware of their surroundings and of the presence of a twin with them in their mother’s womb, said the researchers.'

In Her Own Words: Former Planned Parenthood Director Describes Her First (and Last) Ultrasound-Guided Abortion Procedure: (Again edited for prochoice sensitivities)

At first, the pregnancy tissue didn’t seem aware of the cannula. It gently probed the pregnancy tissue's side, and for a quick second I felt relief. Of course, I thought. The fetus doesn’t feel pain. I had reassured countless women of this as I’d been taught by Planned Parenthood. The fetal tissue feels nothing as it is removed. Get a grip, Abby. This is a simple, quick medical procedure. My head was working hard to control my responses, but I couldn’t shake an inner disquiet that was quickly mounting to horror as I watched the screen.

The next movement was the sudden jerk of a tiny foot as the pregnancy tissue started kicking, as if it were trying to move away from the probing invader. As the cannula pressed its side, the pregnancy tissue began struggling to turn and twist away. It seemed clear to me that it could feel the cannula, and it did not like what it was feeling. And then the doctor’s voice broke through, startling me.

“Beam me up, Scotty,” he said lightheartedly to the nurse. He was telling her to turn on the suction — in an abortion the suction isn’t turned on until the doctor feels he has the cannula in exactly the right place.

I had a sudden urge to yell, “Stop!” To shake the woman and say, “Look at what is happening to your pregnancy tissue! Wake up! Hurry! Stop them!”

But even as I thought those words, I looked at my own hand holding the probe. I was one of “them” performing this act. My eyes shot back to the screen again. The cannula was already being rotated by the doctor, and now I could see the tiny body violently twisting with it. For the briefest moment the pregnancy tissue looked as if it were being wrung like a dishcloth, twirled and squeezed. And then it crumpled and began disappearing into the cannula before my eyes. The last thing I saw was the tiny, perfectly formed backbone sucked into the tube, and then it was gone. And the uterus was empty. Totally empty.
