No. Sadly, sellers of chemical abortion are actively trying to muddy the differences between chemical abortion and birth control pills. Already, there is a similarity in that a woman consumes a pill in order to avoid bearing a child. But that is where the similarities end.
Hormonal birth control (pills, implants, IUDs, injections) is not a guaranteed abortifacient. That is, while it is capable of ending the life of a very new human (and says so on the box), its primary function is not to do so. Hormonal contraception works, in layman’s terms, via four lines of defenses.
Hormonal contraception is administered constantly in order to suppress a woman’s fertility. In order, the four defenses against pregnancy are: Suppressing Ovulation, Thickening of Cervical Fluid, Changing Movement of Cilia in the Fallopian Tubes, and Thinning of the Uterine Lining. That last line of defense, the thinning of the endometrium, is the part that can be abortifacient. If the first three defenses fail and a new human is conceived, that new human (called a blastocyst, at that stage) may not be able to implant and dies as a result. Because of the possibility of abortion, consistent pro-life advocates oppose its use.
Chemical abortion is not a preventative attempt. Human offspring has been created, implanted, and is living and developing. Chemical abortion is the intentional termination of that human life within the first trimester by blocking necessary hormones to end the life then stimulating the expulsion of the remains.
