So it prevents the conception, it's not an abortion.
The emergency contraceptive morning after pill has three modes of action that is it can work in one of three ways:
1.The normal menstrual cycle is altered, delaying ovulation; or
2.Ovulation is inhibited, meaning the egg will not be released from the ovary;
3.It can irritate the lining of the uterus so as to inhibit implantation.
Keep in mind that fertilization occurs in the fallopian tube and that fertilization marks the beginning of
a new human life and the beginning of the pregnancy.
The journey from the fallopian tube to the womb takes between five and seven days during which pregnancy
cannot be readily detected.
Therefore, if a woman ingests emergency contraception after fertilization has taken place the third mode of action can occur.
The lining of the uterus can be altered causing the woman's body to reject the living human embryo, making implantation impossible and the child will die.
This result is called a chemical abortion; therefore emergency contraception is an abortifacient.
Of course I want a girl that been raped or had a date rape pill slipped to be able not to get pregnant.
Under those circumstances a Dr. could 'prescribe' such a pill.
They make 'birth control' pills for recreation sex which don't abort and kill a human being.
