What Are The Chances Of Clarithromycin Affecting My Birth Control

What are the chances of clarithromycin affecting my birth control pill? (Marvelon). Also, it should be noted that I took Plan B 8 hours after "unprotected" sex (I say "unprotected") because I am back on the pill. Also, if I am close to ovulation in my cycle, is Plan B still effective if my birth control pills were affected by my antibiotics?
