"The available evidence for a postfertilization effect is moderately strong, whether hormonal EC is used in the preovulatory, ovulatory, or postovulatory phase of the menstrual cycle. CONCLUSIONS: Based on the present theoretical and empirical evidence, both the Yuzpe regimen and Plan B likely act at times by causing a postfertilization effect, regardless of when in the menstrual cycle they are used. These findings have potential implications in such areas as informed consent, emergency department protocols, and conscience clauses."
There are competing studies and competing conclusions for sure but there is not a single study anywhere that can conclusively state that Plan B can not effect the endometrium and prevent implantation.
So, when you claim that Plan B is NOT an abortofacient that claim is wrong. It certainly may be and every prospective patient should know just that.
