This threat of criminal prosecution is real. In Indiana, its Attorney General threatened an ob-gyn who performed an abortion on a 10 year old from Ohio, even though it was clearly legal at the time (https://thehill.com/homenews/state-watch/3559347-indiana-ag-threatens-license-of-doctor-who-provided-abortion-to-10-year-old-rape-victim/). There is no doubt that some other prosecutors, who are typically elected officials, will use cases to attempt to advance their political careers.
I suspect that, over time, to minimize the risk of prosecution, some health care personnel in these anti-abortion states will presume all women and girls to be pregnant unless proven otherwise and that they will administer pregnancy tests more commonly before starting or continuing treatments that may be dangerous to the unborn. These treatments include immunosuppressive drugs for autoimmune diseases (rheumatoid arthritis, lupus, multiple sclerosis), cancer treatments (radiation, chemotherapy, other drugs), as well as drugs for more common diseases (acne, bacterial infections, coagulation disorders, high blood pressure, manic-depressive disorder, seizures, see https://www.rxlist.com/teratogenic_drugs/definition.htm, https://www.ncbi.nlm.nih.gov/books/NBK553086/). Some physicians may refuse to treat women or girls for these conditions unless it is clear that they cannot become pregnant in the future because they want to eliminate even the possibility of treatment being given during pregnancy and they cannot test every day.
What do you think? I welcome your opinion on how these state anti-abortion laws may affect medical care to women and girls, pregnant or not.
