Very unlikely.: Morning after pill is not perfect, but the chances are slim, especially in light of a negative pregnancy test. If you're worried because you're period is late, keep in mind that the pill can cause menstrual irregularity. Speak with your doctor about this and the two of you can go over other forms of birth control that you can try. Good luck!
