Popes and the Magisterium have recognized throughout RCC history...again, read the linked "Where Peter Is" article...especially the last paragraph regarding the issue of fetal "Personhood"...
-------------------
"What does all this mean? Well, for one thing, it is clear that the Magisterium has acknowledged on multiple occasions that there is a debate about personhood. It is also clear that the Church has not always considered the life of a human person to begin at conception. More recently, the Church has pushed back against the idea that "delayed personhood" is relevant to its position on the sanctity of human life from the moment of conception. It has taught instead that life, from the moment of conception should be treated and respected as a human person. And in this Pope Francis has always been in line with Catholic Tradition."
-------------------
I fully support this summary...we "Should" always Treat and Respect...from conception...the fetus "AS" a person...without the definitive statement it "IS" a person...since there is no RCC Theology that defines the outcomes of 'Failure to Implant'...or 'Miscarriage'...which occur in the Majority of conceptions...nor are there secular/governmental rights firmly established for ALL who live in this nation.
With that said, let's hear what you have to say about "Extenuating Circumstances" that certainly pertain to Unwanted Pregnancies...not unlike "EC's" that come up in determining allowable killings in "Just Wars".
