Hi,
Welcome to ehealthforum,
If you were not ready for pregnancy, you should have considered using emergency contraception or using the regular birth control pills as emergency contraceptive (in higher doses) within 24-48 hours to prevent pregnancy. Starting with the regular birth control pills will not prevent pregnancy from resulting. The chances of pregnancy cannot be ruled out completely. Wait and watch for your periods/withdrawal periods. Look out for development of any other new symptoms if you suspect to be pregnant. If you do not get your periods, or if you suspect to be pregnant, do not start with next birth control pill pack. Visit your doctor/gynecologist for further evaluation and assistance.
Take care.
