I removed my original reply upon realization the poster to whom I responded was likely too angry for debate given the tone of the parent post, which I re-read after sending mine. Perhaps the news is too recent and more time is needed for conversation, I thought. It seems that I was entirely correct...
Below is my reply, which I am re-writing for context, and I will have to encroach on everyone's trust that what I write below completely represents the original. Whether I am a "moron and/or a monster" I will leave for you all to decide.
I will say, though, that for Americans, the abortion issue is out of the courts and in the purview of federal and state legislatures. We need to have these conversations sooner than later, if not now. There is a real concern about maternal health and freedom, just as there is one about rights to life and protection in utero.

I am speaking about the past and present. One should be skeptical of predictions about the future.
The motivation for the decision process you describe is fear. Fear or harm, fear of death. Fear itself is irrational (I do not mean this in a pejorative sense) but powerful emotion, but it is not one that I believe motivates people when they are trying to have children. Pregnancy can have many complications that can be debilitating or even fatal (depression, internal bleeding, sepsis, hormonal dysfunction, and so on), and lack of access to abortion in the case of ectopic pregnancy, for example, is only of many factors that would weight against a potential pregnancy. If lack of access over abortion is an overriding fear for women looking to have children, I suspect that fear could just as easily be replaced by other non-abortion-related dangers. Becoming a parent can be scary, and perhaps now isn't the right time. Maybe later.
Also, I want to stress the earlier point I made about living under laws, good or bad. Women bear children because they want them. I believe this to broadly be true, but the case is especially strong in societies where abortion and more importantly contraception are available. Women bear children because they want to raise them, watch them grow, and start families of their own. Should any complications arise from pregnancy, one adapts and lives with them. Despite the risks, which historically had been far graver until very recently, over 7 billion of us exist. I believe that red state or blue state, abortion or no, people will continue to have children, and they will do so in whatever state they are able to raise them. While it is certainly understandable for women, especially if sexually active, who don't yet want to have children to avoid moving to states with outright abortion bans rather than restrictions to the 1st trimester, I doubt it will be an important consideration for those who want to have them.
To your specific point, if laws are so poorly written that they endanger women's lives, such as in ectopic pregnancies, then I expect the laws will change in response to outrage over deaths. Laws that affect people's lives are unavoidable but can unfortunately cause that to happen (e.g. raising speed limits, drug testing requirements, etc.). However, I am not so pessimistic that to believe that no law can be written as a reasonable compromise. And I never would be so pessimistic so as to give up entirely on elected legislatures and instead choose to live under the fiat of judges in hope that their decisions are optimal. There is certainly precedent for courts to make (very recently, in many eyes) stupidly written, poorly reasoned decisions.
