One of the important things to know during a pregnancy is the date of conception, because that helps determine the probably birth date and much more.

If you've been keeping a conception calendar, then you will know the date that your last period started - the one before the first period you missed. Count the date that your last period began as DAY 1.

On DAY 6 of that cycle, your egg was just being prepared for release into the tubes.

On DAY 14, the egg was actually heading down the tube to meet up with the sperm. So anywhere between DAY 14 and DAY 17 is the most likely date of conception.
