If you had a yeast infection, you should have taken an anti-fungal medication. Diflucan (Fluconazole) is the one time, one dose pill most commonly used for yeast infections. If you had a bacterial infection, like bacterial vaginosis, then antibiotics are used for treatment.
Many antibiotics will decrease the effectiveness of birth control pills. It is recommend that you use a back-up method of birth control (like abstinence or condoms) for the time you’re on the antibiotic and for at least 7 days after you finish the medication. There is no evidence that anti-fungal medications interfere with birth control pills’ effectiveness.
If you took an anti-fungal, and you have been taking your pills correctly & consistently, then pregnancy is unlikely. It can take your body as long as 3 months to become adjusted to being on the pill. During this adjustment time, periods may come early, late or sometimes, not at all. Continue taking your pills as directed. Your period should become regular by your 3rd pack of pills.
If you need peace of mind now, do a home pregnancy test. If it is negative, continue your birth control pills. If you miss 2 periods in a row, notify your doctor. You may need to change pills to allow for more of a bleed during the hormone free week. If your pregnancy test is positive, discontinue your pills. Call your doctor or clinic to discuss your options.
