Second, there’s a question of how long the pregnancy will last.As I discuss in this paper, there’s a great deal of variability in “normal” gestational terms for human babies, so predicting a due date typically has a margin of error of a few weeks on each side of the date. The predicted due date has an impact on the psychology of pregnant women and their partners.However, ultrasound determination of the date of ovulation has the same imprecision as does the ultrasound estimate of the gestational age and, therefore, a precise date of conception cannot usually be determined as with in vitro fertilization. In addition, although a woman is most likely to become pregnant if she has sex on the day of ovulation conception may also occur from live sperm still in her reproductive tract on the day of ovulation if she had sex for up to five days before ovulation [26,27]. Health-care providers define the stage or length of pregnancy differently than many people might think. Logically, one might imagine we represent a pregnancy by how much time has elapsed since conception.

If you have a 28-day menstrual cycle — which is assumed by many healthcare providers — you most likely ovulated on day 14.

Determining the Estimated Due Date The estimated due date (EDD or EDC) is the date that spontaneous onset of labor is expected to occur. Conceptional age, menstrual age, and ultrasound age: a second-trimester comparison of pregnancies of known conception date with pregnancies dated from the last menstrual period.

The due date may be estimated by adding 280 days ( 9 months and 7 days) to the first day of the last menstrual period (LMP). The accuracy of the EDD derived by this method depends on accurate recall by the mother, assumes regular 28 day cycles, and that ovulation and conception occurs on day 14 of the cycle.

If your cycle is a few days longer, you probably ovulated after day 14, and your baby may arrive a few days after your estimated due date.

Knowing how your ovulation date coincided with the potential for conception also may give you a hint as to the sex of the baby you're carrying.
