SB 612[0] in Oklahoma made abortions a felony, punishable by up to 10 years in prison. I'm not sure how many doctors will feel comfortable making that call.
...Especially considering HB 4327 then empowers citizens to stage witch hunts against those providers. Imagine developing a reputation for performing abortions in that situation.
[0] Which defined a "medical emergency" as "a condition which cannot be remedied by delivery of the child in which an abortion is necessary to preserve the life of a pregnant woman whose life is endangered" – a high bar to clear. https://legiscan.com/OK/text/SB612/id/2564710
