Calculating Pregnancy Due Date

Couples, both the man and the woman most often knew what pregnancy due date is. However, most often, both are hesitant on its exact meaning or on how it is accurately determined. Pregnancy due date is the date the baby is expected to be delivered. It is also known as the "estimated date of confinement" (or EDC). In this post, we will learn how pregnancy due date can be accurately determined.

Calculating Pregnancy due date

Pregnancy due date can be determined by calculating with the first day of your menstrual last period, minus three months and adding up seven days into it. This procedure is almost accurate if you are sure with the date of your first day of last menstrual period and have a regular 28-day cycle.



For example, you have the first day of your last menstrual period on June 3, minus three months, that is March 3, plus 7 days. So estimatedly, your pregnancy due date is on March 10.

Calculating weeks you are pregnant

Most medical references will count 40 weeks to complete a pregnancy period. To compute more correctly, you can use your pregnancy due date as the reference and count backwards. The concept of the duration of pregnancy period should be clarified however with the issue of 38 weeks or 40 weeks. To clarify this, we say an average pregnancy lasts 40 weeks, it means that it lasts 38 weeks from the date of conception, and 40 weeks from the last menstrual period.

Converting pregnancy period from weeks to months

Medical specialist and doctors often use weeks as reference when counting pregnancy period. This is because counting by months can be quite confusing as there are different number of days for each month. If you prefer to count by month backwards for 9 months, based on the due date. For example, if your due date is March 10, then count, February 10, January 10 and so forth until you reach the 9th month.

Knowing your pregnancy due date can help you prepare a lot for the coming of the baby. However if you are caught up with the due date and still pregnant, there is no need to panic especially when your 4d scans ultrasound indicates you have a healthy pregnancy. Most women will have pregnancy delivery on the week within the pregnancy due date. It is advised then to keep patience when pregnancy passes the awaited date. Most babies even arrived two weeks after the pregnancy due date. Have a blissful pregnancy!
