You speak as though the death of a bady is a certainty here, which is is not.
(Notice, though, that DP addresses this point, too: “the effect of inhibiting implantation is certainly present, even if this does not mean that such interceptives cause an abortion every time they are used”. Note that this consideration does not ameliorate the CDF’s opposition to methods of interception.

)
You shold note, however, that people put forward the argument that a woman taking the pill is far *less *likely to have miscarriages (through failure to implant) than a woman not on the pill, since unintended miscarriage through failure to implant is such a common occurance anyway.
Perhaps; yet, this argument is an example of consequentialism: “unintended miscarriage through failure to implant is common anyway, so it’s ok if it happens in this case.” As you know, that’s
not valid in the realm of Catholic moral theology.
This is begging the question.
No, it isn’t. Prior to the publication of Humanae Vitae, some Catholic commentators posited that artificial birth control was licit in the framework of Catholic moral theology. Upon the publication of HV, it became clear that this opinion – which might have previously been considered putatively valid – was, in fact, not supported magisterially. That’s what I’m asserting here: the prior assertion of a personal opinion, subsequently refuted by a magisterial document, does not trump the magisterial statement. That’s not ‘begging the question.’ You might disagree with my take on the document; but you can’t dismiss it out of hand as a logical fallacy.
The magesterial document only negates the opinions I cited if one reads it the way you do. As noted, I completely disagree with your reading.
I can see your point, of course: the document clearly intends to address the notion of so-called ‘emergency contraception’. However, if it meant to assert that intent matters, we would expect that it would say so explicitly. Instead, in its statement about the morality of interception and contragestation,
it doesn’t explicitly suggest that intent is relevant. Are you really suggesting that the authors of the document were so short-sighted as to not foresee that, although they meant their statement to be conditional, but expressed it unconditionally anyway, it would be interpreted as unconditional? C’mon, now…
