does this depend on any more than the difference between the catholic and medical definitions of pregnancy (catholic = conception; medical = implantation)? the literature for ulipristal says “Pregnancy should be excluded before Ellaone is administered” and that use as abortificant is off-label ( http://www.ema.europa.eu/humandocs/PDFs/EPAR/ellaone/H-1027-en6.pdf] european evaluation , p. 41).

what is dinardo’s basis for saying, “it can disrupt an established pregnancy weeks after conception has taken place”? i assume his “established pregnancy” is the same as the medical definition of pregnancy.
