What Is My Due Date
Your due date, also known as your estimated date of delivery, is the approximate date your labor might begin. Your estimated due date is commonly calculated by adding 280 days to the date of the first day of your last period, using Naegeles rule. This may vary if you have irregular periods.
It’s worth noting that although predicted due dates are commonly calculated at 280 days, a baby is born on its predicted due date just 5% of the time. 2 A 2020 study published in the International Journal of Obstetrics & Gynaecology suggests a number of factors that can influence the length of your pregnancy, including ethnicity, height, variations in the menstrual cycle, the timing of ovulation, parity and maternal weight. It is for this reason that calculations using Naegeles rule can be considered as an estimate and not a definitive date. 3
What Does It Mean If I Give Birth Before My Due Date
Pre-term birth is defined as birth occurring before week 37, but as you can suspect, inaccurate dating can also be problematic here. There is a diagnostic range of pre-term, with very pre-term being less than 28 weeks and late pre-term being closer to 36 weeks. Based on this spectrum, your doctor can attempt to delay delivery to help the baby grow longer in utero, or if it cannot be delayed, your baby will have to be closely monitored to ensure its health.
Tips For Moms Partner
Many times the male partner does not feel he has a role in a potential pregnancy at this time. However, his health and lifestyle can also affect your future baby. He may need to evaluate his nutrition, medication intake, as well as habits like smoking, and using drugs or alcohol.
Men can also benefit from taking prenatal vitamins or another type of vitamin supplement, including a proper diet, prior to conception.

Your First Three Weeks Of Pregnancy
Hereâs the thing: Because of the way pregnancy is usually measured, youâre not actually pregnant during the first two weeks or so of your pregnancy. Healthcare providers calculate the length of an average pregnancy as 40 weeks, starting from the first day of your last menstrual periodâthis is known as the LMP dating method. So, when youâre 1 week pregnant, youâve only just started your period. At two weeks pregnant, youâre ovulating. And since ovulation happens about 14 days after the start of your period you canât really become pregnant until week 3 at the earliest.It can be mind-bogglingâwe get it. But, for the sake of calculation, and what you and your healthcare provider will consider as 1 and 2 weeks pregnant, youâre not actually pregnant! But although at 1, 2, or 3 weeks pregnant you may not notice any of those very early signs of pregnancy, there may be a lot happening on the inside.

Can An Ultrasound Determine A More Accurate Due Date
Your doctor may adjust your due date during a dating ultrasound, which typically occurs during one of your first appointments. Since healthy embryos grow at a highly predictable rate during the first trimester, measuring the length of the embryo can provide a more accurate estimation of how many weeks pregnant you are.

The Diagnostic Uses Of Pregnancy Ultrasound
Apart from helping to pinpoint the unborn babys due date, pregnancy ultrasounds are used to diagnose a number of conditions including:
- Multiple fetuses
- Health problems with the baby
- Ectopic pregnancy
- Abnormalities of the placenta such as placenta praevia, where the placenta is positioned over the neck of the womb
- The health of the mothers reproductive organs.
What If I Have Irregular Periods Or Long Cycles
Some women have cycles that are consistently longer than the average 28-day cycle. In these cases, a pregnancy wheel can still be used, but some simple calculations are necessary.
The second half of a womans menstrual cycle always lasts for 14 days. This is the time from ovulation to the next menstrual period. If your cycle is 35 days long, for example, then you probably ovulated on day 21.
Once you have a general idea of when you ovulated, you can use an adjusted LMP to find your due date with a pregnancy wheel.
For example, if your menstrual cycle is usually 35 days long and the first day of your LMP was November 1:
After you calculate your adjusted LMP date, simply mark it on the pregnancy wheel and then look at the date where the line crosses. That is your estimated due date.
Some pregnancy wheels may allow you to enter the date of conception which occurs within 72 hours of ovulation instead of the date of your LMP.

Pregnancy Week 36 Fetal Development
Your babys skull is made up of relatively soft and flexible bones. This will allow him or her to go through the birth canal during delivery. Theyll eventually harden during the babys infant years.
Theyll be shedding most of their lanugo, which is the soft downy hair that covered their body. These tiny hairs will mix in with the amniotic fluid. Inside their bowels, their first stool is forming. This is called meconium. Its sterile and your baby wont release it until after birth unless theres any sort of fetal distress.
A Word About Due Dates And Trimesters
After you announce your pregnancy, the first question you’ll probably be asked is “When are you due?” At your first prenatal visit, your health care provider will help you determine an expected delivery date . Your EDD is 40 weeks from the first day of your last menstrual period .
It’s important to remember that your due date is only an estimate most babies are born between 38 and 42 weeks from the first day of their mom’s LMP and only a small percentage of women actually deliver on their due date.
Another common term you’ll hear throughout your pregnancy is trimester. A pregnancy is divided into trimesters:
- the first trimester is from week 1 to the end of week 12
- the second trimester is from week 13 to the end of week 26
- the third trimester is from week 27 to the end of the pregnancy

Calculate Using A Pregnancy Test With Weeks Indicator
All pregnancy tests are designed to detect the pregnancy hormone human chorionic gonadotropin in urine, but some pricier tests offer a weeks indicator that promises to tell how far along you are. Unfortunately, these tests are pretty vague, stating only one to two weeks, two to three weeks or three-plus weeks pregnant. In addition, the tests measure from implantation, not from your LMP. A test might say that youre one to two weeks pregnant but youre actually four weeks pregnant, according to standard pregnancy calculations.

How Do I Calculate My Due Date
You can calculate your due date by using:
The date of your last period
You can calculate your due date if you know the first day of your last menstrual period before you got pregnant. Your due date is 40 weeks after the day you started your last period.
This method is a good way to estimate when your baby is due because many women remember the day they started their period. But it might not always be accurate, especially if you have an irregular menstrual cycle or are on birth control.
The date you conceived
If you know the exact day you conceived, you can use that information to figure out when your baby is due. Count ahead 38 weeks from the day you got pregnant. That day is your due date.
This method is only accurate if youre sure about the day you got pregnant. You may only know the specific day you got pregnant if you know when you ovulated. Ovulation happens when your ovaries release an egg. Usually, women ovulate about 14 days after the first day of their period. You can track your ovulation by:
- Taking your basal body temperature around the time when you think you might be ovulating.
- Tracking your ovulation symptoms, such as ovulation pain and cervical mucus.
- Using an ovulation predictor kit. These kits use your urine to detect when youre ovulating.

Will You Notice Early Signs And Symptoms When You’re 1 Week Pregnant Or 2 Weeks Pregnant
Your journey through pregnancy has officially begun, but as mentioned above, youâre not actually pregnant yet. Remember that healthcare providers calculate your pregnancy as 40 weeks, or 280 days, from the start of your last period. So, if you have a typical 28-day menstrual cycle, the first two weeks are mainly just Aunt Flo doing her thing.
But after two weeks, other things start to happen.
-
One of your ovaries will release an egg around 14 days after the first day of your last period.
-
The egg will travel down one of the fallopian tubes where it may unite with sperm.
Itâs worth noting that sperm can live inside your body for up to five days, and your egg has a lifespan of up to one day. This means your window of fertility is about five days before you ovulate to one day after.What this all means is that you wonât feel any of those very early signs of pregnancy in weeks 1, 2, or possibly even 3. If you have yet to conceive, then it makes sense that you wouldnât notice anything!
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 baby’s 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.

If you’re getting a blood test in your provider’s office, you may get results sooner. These tests also measure the amount of hCG in your bloodstream, but they’re more sensitive than at-home urine tests. Blood tests may be able to detect pregnancy six to eight days after ovulation.
