Due engagement calculation: How many weeks pregnant am I?

The due date, or estimated date of commitment (EDD), is the approximate date when labor is expected to begin.

As this date is just an estimate, you'll probably outset labor one-time in the two weeks before and after your due date.

In fact, simply one in twenty people delivers on their estimated due engagement, which means just v pct of babies worldwide are born on their verbal calculated date.

Gestational historic period vs fetal age

At that place are two ways to mensurate the age of a babe during pregnancy. To rail pregnancy and calculate a due engagement, gestational age is used.

Gestation is the time between the conception date and birth, or how long a person is meaning in weeks. Gestational age is measured from the last menstrual period (LMP) — the first day of your final menstruation — to the electric current date in weeks.

Due date past conception appointment (or ovulation). With this calculation, 266 days of pregnancy are added to the appointment you conceived.

More About Due Engagement Calculations

Method i: Due engagement past terminal menstrual period

There are several ways, or rules, to calculate the due date of a pregnancy past the last menstrual period in addition to the standard i used in the Flo figurer. The following rules are modifications of the standard formula to go more precise results, but because the more information you can add to the calculation, the more than accurate the due engagement may be.

Read on if yous're curious near how these advanced formulas piece of work in item and how you can use them to calculate a more precise due date.

1. Naegele'due south rule

This is the standard method of computing a due date for a pregnancy. Flo as well uses Naegele's rule every bit the main dominion to summate the due date.

The standard formula is as follows:
LMP + 280 days

This dominion considers a regular menstrual cycle to be 28 days (information technology may vary from twenty to 45 days), with ovulation occurring around the 14th mean solar day of the menstrual bike. If your cycle lasts longer, the estimated due date will be afterwards. If you have a shorter wheel, your due engagement will be before.

2. Mittendorf-Williams rule

The Mittendorf-Williams rule is considered more advanced than Naegele's rule, because the more info yous provide, the more accurate the results will be.

This rule is based on a written report that showed that outset pregnancies tend to be slightly longer (an boilerplate of 288 days from LMP), and for subsequent pregnancies, the commitment date is an average of 283 days from LMP.

First, decide the first mean solar day of your last menstrual period.
Adjacent, count dorsum 3 calendar months from that date.
Lastly, add 15 days to that date if it's your first pregnancy, or add together 10 days if it'southward non your showtime pregnancy.

Short formulas look like this:

For outset pregnancies:

LMP – 3 months + 15 days

For subsequent pregnancies:

LMP – 3 months + 10 days

3. Parikh's rule

Parikh's formula is used for irregular cycles, and the expected date of commitment is calculated by calculation 9 months to the last menstrual menses, subtracting 21 days, and then adding the duration 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 dominion, by using information technology, the risk of any potential errors related to calculating your expected due appointment is greatly reduced.

4. Wood's dominion

Forest's method takes into consideration the individual length of the menstrual cycle too as the number of pregnancies a person has experienced.

1. Outset you calculate your expected due date.

For first pregnancies:

LMP + 12 months – (two months and 14 days) = EDD

For subsequent pregnancies:

LMP + 12 months – (2 months and 18 days) = EDD

2. Then you use the expected due date in the equations below.

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 bike) = EDD

Method 2: Due date by day of conception

Yous might think that information technology would exist easier to calculate your due date from the date you conceived by just adding 266 days, only information technology is a lilliputian more than complicated than that. Fifty-fifty if you know the exact date you had sex, the exact date of formulation is almost never known. Why is that?

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

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

Notes:

EDD - Estimated Due Date
LMP - Terminal Menstrual Catamenia (the first day of your last menstruum)
