What about the changes in the uterine wall to prevent implantation? I think different pill formulas act differently, do they not?

I'm taking advantage of your medical training here, feel free to tell me you're a heart surgeon and have no idea!

The "morning after pill" changes the uterine lining so that an already fertilzed egg [a new life] cannot implant, and therefore is destroyed.

The oral contraceptive pill works by an entirely different mechanism. It prevents ovulation entirely. No egg, no fertilization, no new life, no destruction of a new life.

The following kis from a medical website:

"Combined Oral Contraceptives (COCs)

The primary mechanism of action of COCs is the inhibition of ovulation. The release of an egg, which commonly occurs in the middle of the menstrual cycle, is prevented by COCs. Two hormones produced by the pituitary, a gland located at the base of the brain, coordinate the development and release of an egg from the ovary. One is follicle stimulating hormone, abbreviated FSH, and the other is luteinizing hormone, or LH. A surge in both of these hormones ordinarily occurs in the middle of a woman's menstrual cycle. The surge in LH is the trigger for ovulation. COCs inhibit the production of both FSH and LH and consequently prevent ovulation.3

In the very rare cases where ovulation may occur, another contraceptive mechanism of COCs acts to prevent fertilization. COCs have an effect on the cervical mucus. The progestin contained in COCs causes the cervical mucus to become thick and prevents sperm penetration; the sperm can not pass through the cervix and fertilization cannot take place."

The morning after pill destroys a new life. The oral contraceptive pill does not.
