In brief: About BC pills...

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.
That's very important to understand. A home urine pregnancy test gives a reliable result 3 weeks after sex, if one is still worried about possible pregnancy.
