Few antibiotics affect Birth Control; examples inlude rifampin, griseofulvin, and a few HIV medications. For those antibiotics that do affect birth control, the length of time that the effect lasts depends on the mechanism of interference. Contact your health care provider for advice specific to your medication.

It's safest to take 7 active pills after your last antibiotic to ensure full effectiveness. If there aren't 7 active pills left in your pill pack before the placebos, the 7 pills starts the first week of the next pack.

Can amoxcilllin the antibiotic delay your period?

if you're on birth control and you're taking amoxicillin and you have unprotected sex you can get pregnant, because amoxicillin and many other antibiotics can decrease the affectiveness of birth control by half. So if you are on birth control, and you are taking amoxicillin, and you had unprotected sex you could be pregnant. Otherwise you're period could just be late because you are getting over an illness or you're body is fighting an infection.
