I was on a an antibiotic for two days then had sex with my husband a week later i am on the pill and still in my first week. chances of pregnancy?

Pill and antibiotic: The only antibiotic that truly effects birth control is rifampin. Studies have shown that other more common antibiotics have little or no interaction with birth control. Chances of pregnancy should be no greater than baseline.
