due dateA pregnancy calculator is centered on the normal pregnancy duration of nine months. Your starting date will be calculated from the first day of your last menstrual cycle and then forty weeks is added to ascertain the estimated due date.

This 40-week period is equal to 280 days if calculated from day one of the last cycle or 266 days from the conception date.

This method might not be so accurate, but it is still a highly effective way to find out how to calculate your due date or at least to determine the exact birth week or month with close proximity. One of the main reasons why this method might not work all the time is the inability for persons to determine day one of their last menstrual cycle or their determined date is erroneous or false.

Mothers who are unable or uncertain about the determination of their last cycle’s first date might have to do an early ultrasound to calculate the age of the embryo. The embryo’s age would then be deducted to the forty-week period.

At this point, it’s worth mentioning that babies are born prematurely in certain instances due to a number of factors.

In addition, there are cases where babies born sometime after the calculated dates.
So, why should you calculate your date and how you can benefit from doing so?

For one, this calculation will give you a better understanding of the things you can and cannot do. It is important to remember that the months close to the due date will be the most crucial phases of a pregnancy.

As of such, there are some things that you should not do in this period and having knowledge of your due date can help you to determine when you need to stop performing the forbidden actions.

Another thing is that you can have an idea when you will be admitted to the hospital. Generally speaking, expecting mothers are advised to be in the hospital room at least 2 weeks before the date.

When you calculate your due date, you will have a good idea when you should go to the hospital.

Overall, it cannot hurt for you to know how to calculate your due date.
