I know prior to Roe the US had similar facilities that I'm sure were also hotbeds of abuse. "Homes for unwed mothers" was the euphemism, and girls who got knocked up out of wedlock used to get shipped off to them so the rest of society could pretend no one had sex before marriage.
Given that they've been shuttered for decades I assume most unwanted kids born as a result of new bans in red states will just end up in foster care after being removed from some horrorshow situation. That's generally what happens to unwanted kids in burgerland.
The Boothe Homes, run by the Salvation Army, were designed for homeless pregnant women of any age; minors had to go to school, which they provided, and AFAIK, at least towards the end, they could keep their babies if they wanted. The Boothe organization also sponsored a school for pregnant and parenting teens in my hometown until the mid 1980s, when it was fused with the public school district. This school had the same general curriculum as the regular schools, and provided free child care; some people wondered if married girls could go there, and the answer was yes.
However, some of them WERE nightmares. I read a book by a Space Shuttle astronaut whose wife, before he met her, was subjected to this. At 19, in the mid 1960s, she got pregnant, and she and the father wanted to get married but her parents wouldn't allow it because their state required parental permission before age 21. (His parents would have.) She was shipped off to a "maternity home" that was out in the middle of nowhere, and the girls "earned their keep" by being used as slave labor at a bottom-of-the-barrel nursing home, and keeping the baby was not an option, either. (I suspect they were sold, which is another story.) The women were not allowed to send or receive mail or phone calls, nor were they allowed to have visitors. When she returned "home", she and the father, who stayed faithful to her because he loved her, tried to re-establish their relationship, but they just couldn't.
To this day, there are homes, usually Christian-oriented, for homeless pregnant women. I don't have a problem with that, as long as they don't force religion on them, and give them an option about keeping their babies. My old town had such a place; women who didn't have a HS diploma or GED had to go to school, and this place did provide transitional housing for women who kept their babies. Bible study was available, but they were not required to attend, or penalized if they didn't. Many of them were fleeing domestic violence and were more comfortable going there. I remember a story in the newspaper about an elderly person who had died, and left their automobile and the mobile home they lived in and its furnishings to this organization, for them to do as they wished with them. In this case, they were used for someone in the transitional program.
