Well this is in the UK so I don't know what the US situation has anything to do with this.
But anyway, there was a fairly similar case about a decade ago after a 38-week abortion.[1] For reference, 38 weeks is the expected duration of a pregnancy.
Would it be okay to have an abortion during delivery? Right after the onset of labour? 1 minute before? A day before? Where exactly do you put the limit here?

I'm very pro-choice but like, at that point delivering the baby early would have saved its life and ended the pregnancy.
There is a lot of gray area in between, but not many cases fall into it. The previous US situation allowed states to put the dividing line anywhere in there, and that was a compromise acceptable to most. It's not a rigorously defensible answer, but the only rigorous answers are "all" and "none", and both are considered repugnant to most people.
A case like this is incredibly rare, and suggests mental health issues. For that, she should receive treatment. While there is an argument to be made that she should have the right to her bodily autonomy and terminate any pregnancy, it's extremely unlikely that this is what she would want if she were mentally healthy. So this case doesn't inform much about where you might draw a line, and more about how to diagnose somebody who is probably depressed or otherwise not competent.
I am not, of course, qualified to judge her competence. I can only speak in generalities.
This is the same act that deals with murder, rape, bodily harm, child abandonment and more.
The main issue behind this conviction appears to be intent, not that this was simply an ‘accident of ignorance’.

Whether it's disingenuous or just a writer being creative, I can't decide.
