Yes, medication abortion and emergency contraception are different.
The use of emergency contraception does not cause an abortion. In
fact, emergency contraception prevents pregnancy and thereby reduces
the need for induced abortion. [1]
Medical science defines the beginning of pregnancy as the implantation
of a fertilized egg in the lining of a woman's uterus. Implantation
begins five to seven days after fertilization (and is completed several
days later). Emergency contraceptives work before implantation and
not after a woman is already pregnant. When a woman is already pregnant,
emergency contraception does not work. Emergency contraception is
also harmless to the fetus and the pregnant woman. More information
on Emergency Contraception can be obtained at www.not-2-late.com.

Medication abortion works by terminating an existing pregnancy. Thus,
medication abortion only works after fertilization and implantation
have occurred.
