Prior episode likely: Taken the day after umprotected sex, emergency contraception is highly effective, but not perfect. It is more likely that you conceived prior to this episode, but were not aware, and thus did not feel the need to use plan b. You should seek medical care to ascertain how far along you are. I would suggest a transvaginal ultrasound examination, since urine or blood tests won't tell how far you are.
