When you stop taking birth control, you may have what's called breakthrough bleeding. You basically have not been using any birth control for the past week, and in any given month a normal, healthy childbearing aged woman can expect to be 20% likely to get pregnant from frequent, unprotected sex. When you do take the pill, you are about 99% effectively protected from getting pregnant. We can't give you odds, or tell you any more than that.
If you miss your next period, you can take a pregnancy test. It takes roughly 10-14 days after conception for a fertilized egg to make the trip from the fallopian tube and implant in a uterus, so a pregnancy test would not be accurate until around that time (when you normally would expect your period). Some tests claim they can detect the pregnancy hormone up to 5 days before you expect your period, but be aware that for the most accurate results, you need to wait until you miss your period. Doctors normally recommend when you are on antibiotic for an infection, you should still take your birth control, but also use a backup method of birth control (condoms, withdrawal, spermicide, etc.) for the time you are not the medication.
