How To Know Your Pregnancy Due Date
Reviewed by Expert panel

Knowing your pregnancy due date makes it easier to plan everything before your baby arrives. To know your due date, either you can consult with your doctor or you can use reliable and accurate online pregnancy due date calculator. Due date is calculated based on your last menstrual period because there’s absolutely no way anyone would know when did they exactly conceived or ovulated. So, to know your due date by using these calculators you need to remember when your last period started.

How Do These Calculators Work

  • Most online pregnancy due date calculators use a similar method to calculate your due date
  • Your menstrual cycle is assumed to be 28 days long with ovulation occurring on day 14
  • Your due date is estimated to be 40 weeks after your last menstrual period
  • The calculator adds 280 days to your last menstrual period.

How To Use These Calculators

  • In the calculator, first you need to enter your first day of last period
  • Then, you’ll need to adjust your cycle length. As some women’s cycle are not exactly 28 days
  • The calculator will do the rest!

What If You Don’t Know The Date Of Your Last Period Or If You Have Irregular Periods

These due date calculator works best and are accurate when your menstrual cycle is regular and your periods are every 28 days. If you have irregular periods, your cycle varies in length, or you may not know your first day of your periods, then these due date calculator may not give you an accurate result. In times like these you can only rely on your first ultrasound scan, which may give you a more accurate due date result.

Counting Your Pregnancy From The Day Of Ovulating

Note that most women prefer to count their pregnancy from the day they were likely to be ovulating during the month of pregnancy, instead of counting from the first day of last menstrual period. This will give you an estimated date on conception (when you may have conceived), which will usually be about 14 days after the first day of your last menstrual period. So, you will be 2 week further along your pregnancy if you’re calculating it according to your last month period rather than your estimated day of conceiving.

Please remember that every pregnancy is different and your baby might be growing at a different rate, and will only be born when he/she is ready. There are only a few percentages of births that take place on the estimated due date. So, it might be possible for your baby to take a week more or a week less to arrive. Give it time because all we want is a happy and healthy baby.
