“normal” contraceptives are abortifacient.
Some traditional “normal” contraceptive methods are truly contraceptive (i.e., stopping conception as in condoms, diaphragms, spermicides, etc.).
Other hormone delivery based methods like the “pill” or rings, under the skin implants or the like are conception preventives (i.e., hormones that stop fertilization by preventing ovulation) with a small percentage, about 5%, that stops attachment of a fertilized egg if that happens..
This very different from a true abortifacient (aborts a fertilized egg) which is what this ruling covers.
