No: The smoking would increase your risk of adverse effects from the medication, not pregnancy.
Dr. Heidi Fowler

Smoking: Smoking will not cause your oral contraceptive to be less effective. However, a woman who smokes & uses oral contraceptives can have increased risk for heart attack, stroke, and blood clots. Smoking does increase risks if you are pregnant.
