Amoxicillin plan b and birth control effects

Patient: I previously asked a question about amoxicillin, birth control and plan b. You said I ahould use condoms while on amoxicillin and should advise my doctor about using plan b. If I were to use plan b can you tell me if there would be any side effects or problems that may occur if doing so while taking orthotrcyclen, amoxicillin and plan b during the same time frame?
