Yes: It depends how long you took antibiotics and for what reason. They decrease the efficacy of seasonique. Use condoms while you take antibiotics for the remainder of the pack. Do a pregnancy test 28 days from the course of antibiotics. Consider nexplanon/ iud for contraception!

Yes: As you know there was no need for Plan B if you were taking the pill as directed. However antibiotics can reduce the effectiveness of your pill.
