Hi,
Welcome to ehealthforum,
If you have been regular in taking your birth control pills at scheduled time daily, and have not missed taking any active pills, you should have the protection. However, chances of contraceptive failure cannot be ruled out completely. You can consider taking emergency contraception if you are worried abut pregnancy. Alternatively, you can consider waiting and watching for your periods/withdrawal bleeding. If periods do not start within 10 days of expected period dates, or if you get abnormal periods, or if you suspect chances of pregnancy, consider visiting your doctor/gynecologist at the earliest for thorough examination (to confirm pregnancy related changes/signs in body) and blood/serum HCG level test (to confirm/rule out pregnancy accurately).
Take care.
