The primary purposes of the morning-after pill are 1) the prevention of ovulation and 2) the prevention of fertilization. The morning-after pill is abortive if and only if it has failed to do its job on counts 1 and 2 but somehow does its job on count 3, which is the prevention of implantation. If you’re going to make a statement like “these pills do end human lives” then you should be making the same claim about any routine medical procedure involving anesthesia.

Ethinyl estradiol and levonorgestrel are used together in this product as an emergency contraceptive (EC) to prevent pregnancy after contraceptive failure or unprotected intercourse. Ethinyl estradiol and levonorgestrel prevent ovulation (the release of an egg from an ovary), disrupt fertilization (joining of the egg and sperm), and inhibit implantation (attachment of a fertilized egg to the uterus).
At the very bottom of the page, after repeatedly stating that it won't terminate a pregnancy and isn't harmful if you're pregnant, it says: You should not take Plan B® One-Step if you are already pregnant.
Hmmmmm.
