The general rule is that you must use the birth control pills for at least 7 consecutive days before they are effective. It is impossible to know how much protection one has after 6 days. Taking Plan B within 24 to 72 hours after the unprotected intercourse would have been an option. Plan B can be effective when taken as late as 120 (5 days) after unprotected sex. Taking Plan B after 5 or more days would probably not be effective.
Anytime you have unprotected intercourse, there is the risk of pregnancy.
In the meantime, continue taking your pills every day, around the same time. It may take your body 1-3 months to become adjusted to being on the pills. You may experience some irregular bleeding or spotting, Your period may be a little earlier or later than usual. If your next period is more than 1 week late, do a pregnency test.
