People actually do delay abortions, and do go 8 months without noticing (or at least pretending not to notice). This isnt even that uncommon in poor inner city communities.
My wife does OB. I here about this shit all the time. You are just talking out of your ass. And for my wife in several years and thousands of patients there was literally one maternal fatality, where the mother hemorrhaged and bled to death AFTER a normal delivery, this law would have done nothing for.
I could ask, but I doubt she had a single case where there was actual indication at 24-30 weeks a mother should abort a pregnancy at that time because there was a significant immediate risk to her own health. And I am pretty confident if such a scenario did come up a women could get an abortion in NY without this new law.
Serious maternal health issues do come up occasionally, but in the 35-40 week range, where the question is whether to do a C section and get the baby out a little early or not.
