Always protected: A woman who is properly taking her birth control pills, and is beyond her first pack of pills, has contraceptive protection ALL the time, regardless of where she is in her pill pack. Adding condoms helps prevent diseases, and may decrease vaginal odor or discharge (by not having disintegrating sperm/semen hang around inside her vagina). Bactrim (sulfamethoxazole and trimethoprim) itself should not affect BC pills effectiveness.
