Sorry, I’m not a doctor. Find one and ask them.
So you’re saying that if a woman is at risk of serious illness or death, she should not be allowed* to terminate the pregnancy unless it’s almost absolutely certain that it will cause her death (i.e., to the same level as an ectopic pregnancy)? What’s your cutoff for when the woman is allowed to kill the fetus to preserve her own health or life? Even ectopic pregnancies aren’t *certain *death–merely obscenely likely.
*If you separate your religious beliefs from your political ones, feel free to amend this in such a way that it applies to what is “allowed” morally versus legally.
