What is conception? How to find your Conception Date

conception Date: Conception is the time when a woman ovulates and sperm meets the egg to further form the embryo. Sperm can live for 3-5 days. We take an example to clear the idea – Suppose a couple had intercourse on the 10th, but the partner may not ovulate till the 13th, so conception would occur on or after 13th. It is nothing but the exact date when a woman’s egg is fertilized.

Conception Date:

Many couples want to know their baby’s conception date and the first question which arises to them after the news of pregnancy is “When is the baby due date?” It logically seems that the day of a couple’s intercourse is the conception date but that’s not always the case because it takes time for the sperm to fertilize with the egg. There are a couple of methods to know the conception date accurately but that would just be an estimate.

Methods to find your Conception Date:

There are a few ways through which one can figure out their conception date and that just takes a bit of research and knowledge about your body

An ultrasound may help!

Getting an ultrasound within one week may help the couple know the conception date based on the gestational age. This process may prove not so accurate when the 1 week time has passed because the gestational date is not measured by the conception date, but by the date of a woman’s last period.  An ultrasound doctor may examine the baby’s size and then accurately estimate the date on which the baby was conceived. It’s the simplest method one can go for knowing their conception method.

Conception based on Ovulation:

One cannot conceive unless they ovulate which means that if you have been keeping a record of your ovulation date, you may be able to intercept the correct conception date. In a regular 28-day period cycle, conception usually occurs two weeks after the first day of your last period. For instance, if your period started on July 10th, conception would occur around July 24th.

Determining your period cycle:

It is not necessary that a woman has the regular 28-day cycle and thus they do not ovulate 2 weeks after the first day of their last period. The solution to this problem is to chart your cycle and know the exact number of days to calculate your conception with reference to the ovulation. If your cycle is less than 28 days, then deduce the number 14 by each day your cycle is shorter. Alternatively, if your cycle is greater than 28 days, take the number 14 and each extra day by which your cycle exceeds. For reference, say you have a 32 day cycle, then you ovulated 18 days after first day of your last period.

Online Conception Calculators:

The advancement of the era allows you to calculate your Conception Date in a few minutes on your fingertips. There are many websites and online Conception date calculators which help you determine your Conception date easily. The calculator asks about the due date or the date for your last menstrual period and simply tells you a range in which the conception date was to be expected. However these calculators are based on the regular 28-day cycle and may give out incorrect results if your cycle varies from the regular one.


It is fun to know when your baby was conceived and started to grow but it has no use with the physiological growth or health of the baby. The Conception date has no mere significance for your baby’s medical conditions. Understanding when conception may occur may help a woman in to plan her pregnancy, but it will not affect the outcome of her pregnancy.
