&gt;99.5% not pregnant: The typical failure rate of a progesterone only oral contraceptive is about 5% per year. If you are taking the pill correctly, your chances of pregnancy from this episode of intercourse are less than .5%. (You have a greater than 99.5% chance that you are not pregnant). Best wishes!
