Conception: Pregnancy is dated from the LMP. Every pregnant female should have access to at least one website that has all of the tools to answer nearly every question about pregnancy. Here is a tool everyone should know about: http://www.babymed.com/conception-calculator. It is a conception calculator and will answer every dating question possible about your pregnancy.

Ultrasound: That's enough of a discrepancy between your LMP and the ultrasound dates to change your due date.
