I don't know the mechanism of this new pill, but the standard contraceptive pill that's been in use for decades is a misnomer. It doesn't merely prevent conception, but also acts by preventing the implantation of an already-conceived human life--which now lives within a fertilized human ovum (egg)--into the uterus to receive nourishment and grow. If not allowed to implant, this new, unique-for-all-time, human individual dies.
The reality is that a fertilized egg contains the first cell, or cells, of a new human being--who, if left undisturbed, will be born about 9 months later.
So, the "Pill," in such cases, has missed the boat for preventing conception, and is simply aborting someone already conceived.
The question would be how, exactly, does this newer pill do what it does?
The old pill stops the ovaries from producing an egg each month. Please source what I believe is misinformation.
