No, the Pill and the Morning-After Pill do NOT cause abortions by anyone’s standards, not even the conservative Christian standard.
They do not work by preventing implantation, but by preventing ovulation/fertilization. Without fertilization, there can be no conception.
The notion that morning-after pills prevent eggs from implanting stems from the Food and Drug Administration’s decision during the drug-approval process to mention that possibility on the label–despite lack of scientific proof, scientists say, and objections by the manufacturer of Plan B, the pill on the market the longest.
Leading scientists say studies since then provide strong evidence that Plan B does not prevent implantation, and no proof that a newer type of pill, Ella, does. Some abortion opponents said they remain unconvinced….
Experts say implantation was likely placed on the label partly because daily birth control pills, some of which contain Plan B’s active ingredient, appear to alter the endometrium, the lining of the uterus into which fertilized eggs implant. Altering the endometrium has not been proven to interfere with implantation.
But in any case, scientists say that unlike the accumulating doses of daily birth control pills, the one-shot dose in morning-after pills does not have time to affect the uterine lining….
Dr. Trussell of Princeton said that if morning-after pills worked after eggs were fertilized, they would prevent pregnancy better than they do. The pregnancy prevention rates are probably lower than scientists and pill makers originally thought, he said–in some studies as low as 52 percent for Plan B and 62 percent for Ella.
By contrast, scientists say, research suggests that the only other officially approved form of emergency contraception, the copper intrauterine device (also a daily birth control method), can work to prevent pregnancy after an egg has been fertilized. –Pam Belluck, Abortion Qualms on Morning-After Pill May Be Unfounded
Note that if you don’t take the Pill regularly, it won’t protect you from pregnancy. Which also does not support the idea that it’s an abortifacient.
Here’s a Lutheran paper on the subject: Birth Control Pills: Contraceptive or Abortifacient?
The following article, from a Catholic health journal, argues that Plan B emergency contraception does not cause abortions, as the Church would understand them, that it does not abort fertilized eggs: Plan B: How it Works: Science shows it is not an abortifacient
