The drug Plan B is also artificial progestin and therefore impedes the sperm from entering the uterus in the same way as the IUD. But the drug can also stop the ovaries from releasing an egg. If an egg has already been released, Plan B can slow down the movement of the egg. By slowing down both the egg and the sperm, it prevents fertilization.Is that true if the embryo hasn’t made it’s way down the fallopian tubes? Meaning, does Plan B still work in a way that might make the womb hostile to the embryo who has not yet implanted?
The effectiveness of Plan B drops considerably if given more than two days after intercourse. But even at its peak of effectiveness, it is only works 50 percent to 80 percent of the time. Some have argued that Plan B acts after fertilization by changing the uterine lining is such a way that implantation is impossible.
But according to Dr. Sandra Reznik, who also wrote for the January-February 2010 edition of CHA’s Health Progress, if Plan B “involved a change in the endometrium, then one would expect a higher rate of success [in preventing pregnancy]. … Taken together, there are biological, clinical and epidemiological data clearly indicating that Plan B’s mechanism of action involves only pre-fertilization events.”

I’m of course no doctor or researcher, so If you have evidence of the post-fertilization claim, feel free to cite your source. I’m always happy to read.
