According to American Congress of Obstetricians and Gynecologists, the main methods to calculate gestational age are:
- Directly calculating the days since the beginning of the last menstrual period
- Early obstetric ultrasound, comparing the size of an embryo or fetus to that of a reference group of pregnancies of known gestational age , and using the mean gestational age of other embryos or fetuses of the same size. If the gestational age as calculated from an early ultrasound is contradictory to the one calculated directly from the last menstrual period, it is still the one from the early ultrasound that is used for the rest of the pregnancy.
- In case of in vitro fertilization, calculating days since oocyte retrieval or co-incubation and adding 14 days.
- Ultrasound measurement in the first trimester is generally considered to be the most accurate way to measure gestational age.

How Is My Due Date Calculated
There are several ways your due date is determined. If you happen to know the day you conceived, you can count 38 weeks from that day to find your due date.
But very few expectant moms know exactly when they conceived. Even if you only had sex once during your fertile period, you wouldn’t conceive on that day unless you happen to be ovulating. Sperm can live for up to five days inside your fallopian tubes. So, it could be up to five days after you have sex that you release an egg and it gets fertilized by a waiting sperm. That’s the day you conceive.
So, without knowing the day of conception, how does anyone determine a due date?

As soon as you find out you’re pregnant, you’ll probably start counting nine months on your fingers to figure out when your baby will be born. But then your healthcare provider might mention that you’re likely to go into labor once your 40 weeks along, and things don’t seem to line up, because 40 weeks sounds more like 10 months.
Your gestational period is in fact 40 weeks long, but it starts counting on the first day of your last period. You aren’t actually pregnant during weeks 1 and 2, and by the time you see a positive result on a pregnancy test, you are already considered four weeks pregnant. The first month has already passed!
You can count your gestational period in weeks or months. Your healthcare provider will use weeks, but you might start using months in conversation when you get further along. Your friends and coworkers might find “I’m 8 months” easier to understand than “I’m 32 weeks.”

What Is Gestational Age Can It Be Different Than What The Calculator Shows
Gestational age is the term used to describe how far along the pregnancy is and how long baby has been gestating .
If you get an ultrasound you may notice a GA on the image with a number of weeks and days. This figure is based on how the baby is measuring, not on your LMP, which the due date calculator uses.
Its normal for these dates to not match up perfectly. If there are significant differences in the dates, your doctor may want to dig deeper to determine conception date. As a result, your midwife or doctor may change your due date based on the ultrasound gestational age.
Early ultrasounds are very accurate when dating a pregnancy and can be helpful if you dont know your LMP or your periods are irregular.

How Can I Work Out My Due Date
After finding out you’re pregnant, you will want to know how pregnant you are and when your baby is likely to be born. This can be done by working out your estimated due date.
You can calculate your babys estimated due date based on the date of the first day of your last menstrual period . Your baby will be due around 40 weeks after the first day of your LMP. This method is particularly accurate if you have a regular menstrual cycle. For example, if you have a regular 28-day cycle, add 7 days to the date of the rst day of your last period, then add 9 months.
If your cycle is longer or shorter than 28 days or irregular, working out your due date using the first day of your LMP can be more difficult and may also be more unreliable.
Another way your due date can be calculated is by using ultrasound. By measuring your babys size, doctors can work out how far along your pregnancy is. In early pregnancy your doctor will measure the length from your babys head to your babys bottom. This is called the crown-rump length or CRL. Later in pregnancy, your doctor can measure different parts of your babys body, including your babys head, thigh bone and abdomen to work out an average size and an estimated due date.

Dating Pregnancy Using Ultrasound
Ultrasound in the first trimester is the most accurate method of dating pregnancy. During the scan, baby is measured and the age of pregnancy is estimated by comparing babys size against recorded averages. If there is a significant difference between gestational age according to LMP and gestational age according to the ultrasound, you may be given a new gestational age and due date based on the ultrasound measurements.
Your pregnancy may also be dated by ultrasound measurement if an LMP formula was not appropriate for your pregnancy for any reason. LMP formulas are not suitable in several situations including the following: LMP is not known or is not certain, birth control pills were taken in the two months before LMP, the menstrual cycle is irregular, you are carrying multiples .
Although the age of pregnancy based on ultrasound measurements is more accurate than the age of pregnancy based on LMP, both are estimates and not definitive statements.

However, there is a chance that your overall hCG levels will be up to 50% higher than what is considered the normal range for a single pregnancy.

What Does It Mean If My Doctor Changes My Due Date
Your doctor may change your due date if your fetus is significantly smaller or larger than the average fetus at your particular stage of pregnancy.
Generally, your doctor orders an ultrasound to determine the gestational age of your baby when theres a history of irregular periods, when the date of your LMP is uncertain, or when conception occurred despite oral contraceptive use.
An ultrasound allows your doctor to measure the crown-rump length the length of the fetus from one end to the other.
During the first trimester, this measurement provides the most accurate estimation for the age of the baby. Your doctor may change your due date based on the ultrasound measurement.
This is most likely to occur in the first trimester, especially if the date estimated by the ultrasound differs by more than one week from the date estimated by your doctor based on your LMP.
In the second trimester, an ultrasound is less accurate and your doctor probably wont adjust your date unless the estimates vary by more than two weeks.
The third trimester is the least accurate time to date a pregnancy. Estimates based on an ultrasound can be off by as much as three weeks, so doctors rarely adjust dates during the third trimester.
However, its not uncommon for a doctor to perform an ultrasound in the third trimester if theyre thinking about changing your date.
Pregnancy Weeks Vs Months
Planning for a nine-month pregnancy can be confusing if you look at the total number of weeks in the average pregnancy. When you break down the numbers, it would seem that pregnancy lasts 10 months, not nine.
There are about 40 weeks in a full-term pregnancy. If you assume that a month is exactly four weeks long, that makes 10 months of pregnancy. The problem with this calculation is that it assumes that each month lasts 28 days. But most of our calendar months last 30 or 31 days.
To confuse matters even more, there is also the issue of when you actually became pregnant. While an exact date may not matter to everyone, you can estimate the date based on testing. By the time you have a positive pregnancy test, you are usually about four weeks pregnant.
The truth is that a full-term pregnancy lasts between nine and 10 months. To establish clarity about your stage of pregnancy and estimated due date, your practitioner will track your pregnancy in weeks rather than months.
