You are correct it happened in the 60's and way before alot. That was the term because I heard my mother talk about it when was growing up. They used to call it D&C. That went on and it will still go on even if Abortion is outlawed.
Another big difference these days from times past ... today chemical abortions are safe and can be done in privacy. From what I've heard certain groups are already assembling packages with the needed drugs and instructions to send by mail.
Of course they only work in the first two months or so.
"They used to call it"? They still call it a d&c, dilation and curettage. It's done for many reasons, and you're right to assume that sympathetic doctors will continue to do them.
