Calculation of Due date of pregnancy
Although the estimated date of conception is the day you first become pregnant, most people don’t count pregnancy from that date. That’s because there’s no way to know for sure on which day you actually ovulated and conceived.
You can work out the date your baby is likely to be born by counting from the first day of your last menstrual period (LMP). This is how most doctors will work out your due date.
Your pregnancy should last approximately nine calendar months and seven days, or 40 weeks. So add this length of time from the first day of your last normal period to get an idea of your due date.
It’s quite hard to get a spot-on due date this way. The calculation works best if your menstrual cycle is regular and your period begins predictably every 28 days. You can use our online Due date calculator also known as Pregnancy calculator which will help you work out your baby’s due date.
Your doctor will calculate due date of pregnancy when you meet her at your first antenatal appointment. She will write down your due date in your maternity file. You may see the date written as expected date of delivery, or EDD.
Many women’s menstrual cycles vary in length. So counting from the first day of your LMP may not give you a date you can rely on. Your first ultrasound scan will give you a more accurate due date for your baby.
Exact way of finding the due date of pregnancy
The person carrying out the ultrasound scan, called a ultrasound doctor, will work out how pregnant you are by looking at your baby on the screen.
This scan will tell you exactly how many weeks into your pregnancy you are, based on the stage of development your baby is at. The doctor will also check if you’re carrying twins, or more.
