Conception describes the point in time at which the egg and sperm unite which usually happens a few days after sex, not instantly after sex. You know the date on which you had sex, not the date on which you became pregnant. It is best to take Plan B in less than 72 hours after you've had unprotected sex. However, it is not 100% effective. It works like one large dose of birth control. It makes any egg that may be tumbling towards your uterus (if you're ovulating) infertile so that sperm cannot penetrate it and cause pregnancy. If egg and sperm unite before you take the pill, it will not terminate the pregnancy. It is possible that an egg was released after the effects of the pill wore off and that sperm was still present and fertilized that egg. If you're pregnant after trying to use Plan B to prevent conception, obviously Plan B failed.
