One about killed a woman by not identifying her pregnancy is ectopic. Many anti abortion folks are convinced that even ectopic pregnancies can be viable.
These places promise things like free pregnancy tests and medical advice to get people in the door.
They really just exist to pressure women into not getting abortions. They will lie through their teeth - all the classics, like suggesting that an abortion makes it impossible to get pregnant again, or that abortion causes cancer - they’ll say anything to prevent an abortion.
They are pretty much completely unregulated, and present themselves as secular non profits.
Mostly Planned Parenthood. There are a few other places, but they have less to spend on advertising.
I’ve thought about calling up a few as a trans man to see how they’d respond. The reaction would probably help identify how legitimate they were.
