I am on the same page as Gian2hard. It would be a "putative crime due to a mistake of fact.
" , I mean related to the charges of self inducing abortion (if I understood the question well).
That could be an enough defense, or the charges could dismissed at all (I am not a lawyer, let alone educated on the American legal system or something).
I don´t know if there would be another charge, because she harmed her body, then it could regarded as another felony or unlawful act. But then, perhaps she would do community service or something.
Or perhaps not. It would just be "a mistake of fact" that would work in her defense.
Plus, they have differences in law from a state to the other, in 2010 an Iowan woman found herself arrested because she fell down the stairs (she didn´t knew for certain if she was pregnant) and it was considered as a violent act against an unborn. Then the charge was dropped afterwards.https://rewire.news/article/2010/02/15/ ... wn-stairs/
