How to Calculate Possible Due Date

No sooner than you get pregnant, you want to know your possible due date, right? That is normal. As soon as you find out that you are pregnant, you will start calculating when you are due. You don’t need to worry so much about that because your doctor will help you with this during your first appointment itself. He might conduct a vaginal ultrasound to give you more accurate results.

If you are highly impatient and do not want to wait that long, you can do the estimation yourself. Here are some tips to find out your possible due date.

Forty Weeks

Many people say that the gestation period is nine months long. To say it correctly, it is forty weeks long. So you can calculate 40 weeks from the day you got pregnant.

However, don’t rely on this calculation entirely. Every baby will not take forty weeks. Some may be ready to enter the world beforehand while the others may take some more time. Forty weeks is just an estimate for you and nothing more than that so that you can plan accordingly.

Thus, if your baby decides to show up before your calculated due date, don’t be too surprised!

Menstrual period

Tracking your menstrual cycle will not just help you find out when you are ovulating in order to make things easier for you but it will also help you find out your possible due date. You have to start calculating from the first day of your last menstrual period.

If you haven’t been tracking your menstrual cycle, then you should come up with estimation. If you are sure about the dates, you will be more accurate. That is very obvious. If you are not sure about the math, things can be a little more difficult for you and you will end up with a general date.


Now that you know the first date of your last menstrual cycle or at least a general idea, you can go ahead and do the math. Count forty weeks from the date you have at hand and you will have the possible due date! To be exact, you should count 280 days.

Another thing that you can do in case you don’t know when your first date of last menstrual cycle was is count from the day you conceived. If you absolutely know of your date of conception, add around 266 days and you will have your possible due date.


You would have known by now that nothing can be affirmed here. You can’t say that you surely know when your due date will be. You can only have an estimate because even though you know the right date of conception or the first date of your last menstrual cycle, there are other factors that come into play.

Your baby may come early or she may decide to live inside you a little long. Know that the due date does not matter as long as your baby is safe and healthy!

Visit the doctor once you find out you are pregnant so that you get a general idea.
