Will bactrim (sulfamethoxazole and trimethoprim) affect my birth control pills?

No: Only antibiotics for the treatment of tuberculosis like rifampin will affect the efficacy of your birth control pills. Continue taking your pills daily and don't miss any and your effectiveness should be >95% effective.
