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

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.

While it may be desirable to know, the time of conception is actually fairly hard to pin down.

While it may be fun to determine your conception date in order to know the exact moment your baby began to grow, knowing it is not medically necessary.

Your due date is typically determined from the first day of your last menstrual cycle and is only an estimate of when the baby will be born.If you know or suspect your conception date, you may notice that it doesn't match up with how many weeks along you are.That is because gestational age is measured not by conception date, but by the date of your last period.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.Author and physician Landrum Shettles says in his book, (Doubleday), that the father should not have an ejaculation for the three days before the "target date" (a day or two before ovulation) if you're trying for a boy.If you have a regular 28-day cycle, conception usually occurs about two weeks after the first day of your last period.
