Morning After Pill? Sin? Abortion? Contraception?

[SDG]

Wiki says it is Emergency contraception ...

Emergency contraception (EC), or emergency postcoital contraception, refers to contraceptive measures that, if taken after intercourse, may prevent pregnancy.

Forms of EC include:

Emergency contraceptive pills (ECPs)—sometimes simply referred to as emergency contraceptives (ECs) or the "morning-after pill"—are drugs that act both to prevent ovulation or fertilization and possibly post-fertilization implantation of a blastocyst (embryo). ECPs are distinct from medical abortion methods that act after implantation.[1]

Intrauterine devices (IUDs)—usually used as a primary contraception method, but sometimes used as emergency contraception.

As its name implies, EC is intended for occasional use, when primary means of contraception fail. Since EC methods act before implantation, they are medically and legally considered forms of contraception. Some scientists believe that EC may possibly act after fertilization (see Mechanism of action).

Some religious conservatives consider EC to be an abortifacient.
