More than Well-nigh Due Date Calculations

Method 1: Due date by concluding menstrual period

There are several means, or rules, to calculate the due date of a pregnancy by the last menstrual period in add-on to the standard one used in the Flo reckoner. The following rules are modifications of the standard formula to become more precise results, just because the more information y'all tin add to the calculation, the more accurate the due appointment may exist.

Read on if you lot're curious well-nigh how these advanced formulas work in detail and how you can use them to calculate a more precise due date.

ane. Naegele'due south rule

This is the standard method of calculating a due appointment for a pregnancy. Flo likewise uses Naegele'south rule as the main rule to calculate the due date.

The standard formula is as follows:
LMP + 280 days

This dominion considers a regular menstrual cycle to be 28 days (it may vary from 20 to 45 days), with ovulation occurring around the 14th day of the menstrual cycle. If your bike lasts longer, the estimated due appointment will exist later. If you lot have a shorter cycle, your due date will be earlier.

two. Mittendorf-Williams dominion

The Mittendorf-Williams rule is considered more avant-garde than Naegele's rule, considering the more info you provide, the more than accurate the results volition exist.

This rule is based on a study that showed that first pregnancies tend to be slightly longer (an average of 288 days from LMP), and for subsequent pregnancies, the delivery date is an average of 283 days from LMP.

Starting time, determine the get-go 24-hour interval of your final menstrual period.
Next, count back 3 calendar months from that date.
Lastly, add together xv days to that date if it's your first pregnancy, or add together 10 days if it's not your first pregnancy.

Brusque formulas await similar this:

For first pregnancies:

LMP – iii months + 15 days

For subsequent pregnancies:

LMP – 3 months + ten days

three. Parikh's rule

Parikh's formula is used for irregular cycles, and the expected date of commitment is calculated by adding 9 months to the last menstrual catamenia, subtracting 21 days, and and so adding the elapsing of previous cycles.

In short, use this formula:
LMP + 280 days – 21 days + the length of previous cycles*
*The average cycle length

Even though this formula is considered a modification of Naegele's rule, by using it, the risk of whatever potential errors related to calculating your expected due engagement is greatly reduced.

4. Forest's dominion

Wood'due south method takes into consideration the individual length of the menstrual cycle equally well as the number of pregnancies a person has experienced.

1. First yous calculate your expected due engagement.

For commencement pregnancies:

LMP + 12 months – (2 months and fourteen days) = EDD

For subsequent pregnancies:

LMP + 12 months – (2 months and xviii days) = EDD

2. Then you lot employ the expected due date in the equations beneath.

For cycles longer than 28 days:

EDD + (actual length of cycle – 28 days) = EDD

For cycles shorter than 28 days:

EDD – (28 days – actual length of wheel) = EDD

Method 2: Due date by mean solar day of conception

You might think that information technology would be easier to calculate your due date from the date you conceived by simply adding 266 days, but it is a niggling more than complicated than that. Fifty-fifty if you know the exact date you had sex, the exact appointment of conception is almost never known. Why is that?

Because information technology can be challenging to determine the exact date of ovulation and thus the engagement of formulation. Sperm can alive in the female person body for up to 5 days, and the egg tin live for 24 hours afterwards information technology's released from the ovary.

Therefore, conception tin can occur several days after you've had unprotected intercourse.

Notes:

EDD - Estimated Due Appointment
LMP - Concluding Menstrual Period (the commencement twenty-four hours of your terminal menses)
