Not yet: Though it' s unlikely that you are pregnant based on the scenario you describe, no form of birth control can guarantee 100% prevention of pregnancy. I recommend a home pregnancy test first. If negative, no worries. If positive, consult with your gynecologist before taking any medication.

Essentially no risk: If you were taking your bcp as prescribed and this was your off week, during which you had your period, you will have very, very low risk of getting pregnant. Resume taking your bcp as prescribed for the start of your 28 day cycle. Meanwhile you may want to refresh your education a bit about other hazards of unprotected sex, such as sexually transmitted diseases.
