Pop culture has long portrayed pregnancy as a ix-month countdown to birth. Only how long is pregnancy? Working this out can actually exist a little fleck more complicated than that.

"From a medical standpoint, doctors always talk in weeks and days," says obstetrician, gynecologist (OB-GYN), and Flo medical board member Dr. Charlsie Celestine. "A full-term pregnancy is 40 weeks long, which equals 10 months. However commonly, people talk about pregnancy as beingness 9 months long."

Hang on. ten months, not nine? How can that be the case? According to the National Health Service in the United kingdom of great britain and northern ireland, the average length of human gestation is 280 days or xl weeks, and that time starts from the first twenty-four hours of your last period, when you're not technically significant yet. That's because ovulation (which happens midway through your cycle) and fertilization haven't occurred yet — simply more than on that later.

No ii pregnancies are the aforementioned, and pregnancies can vary in length. Here, Dr. Celestine explains why pregnancy is often referred to as nine months and how your due appointment is calculated.

How long is a total-term pregnancy in months and weeks?

If nigh full-term pregnancies (when a infant is born between 39 weeks and 40 weeks and 6 days) last ten months, then you'll probably be wondering where the idea of nine months comes from.

This confusion almost how nosotros refer to pregnancy length could exist related to the fact that most people don't find out that they're pregnant until they've missed a menstruum, which is already approximately four weeks into the pregnancy.

"Ovulation [when an egg is released from your ovaries ready for fertilization] typically takes place around two weeks after the first day of your concluding menstruum, and this is when a baby would be conceived. But because you won't know that you're pregnant until you've missed your side by side flow, approximately ii weeks later, you'll already be iv weeks pregnant when you get your positive test event. At that point, y'all'll have approximately 36 more weeks to go," Dr. Celestine says.

And 36 weeks equates to ix calendar months, which is why many people unremarkably refer to pregnancy as existence nine months long. Makes sense, right?

How is a due date calculated and how exercise I know my current week of pregnancy?

If you suspect that you're pregnant or accept taken an at-home pregnancy test that's come back positive, the best adjacent step is to reach out to your health care provider. During your offset appointment, they will exist able to confirm that you're significant and work out your estimated due date.

About health intendance providers apply Naegele's rule to calculate the babe'southward due engagement. This rule was invented by the obstetrician Franz Naegele in the 19th century, and information technology's still being used today. It means your health care provider will work out your due date like this:

Firstly, your health intendance provider volition determine the outset solar day of your terminal period.
Secondly, they volition then count back three agenda months from that engagement.
Thirdly, they will add one year and seven days to that date. Rather than working this out with a pen and newspaper, your health care provider volition use a due date estimator to guess your engagement.

Knowing your due date tin feel similar a milestone moment in your pregnancy — but don't worry, y'all aren't expected to figure information technology out yourself. If y'all rail your periods with an app like Flo, then you'll exist able to tell your medical professional when the outset day of your last catamenia was. They will then exist able to practice the calculation for you. You can also utilize a due date calculator.

Does an irregular cycle affect your due date?

Tracking your menstruum can exist a piffling bit more difficult if y'all have an irregular bike. However, if this is something you experience, don't worry. An irregular cycle won't affect the length of your pregnancy. "A lot of people's cycles are irregular, and so sometimes we can't utilise your period equally a predictor. We have to measure the fetus on an ultrasound instead," says Dr. Celestine.

During your first trimester (the first fourteen weeks of pregnancy), how far forth you are (gestational age of pregnancy) is determined by your babe's crown-rump length. "This is literally the length of the fetus every bit seen on the ultrasound," explains Dr. Celestine. Your health care provider volition notation how long your babe is in centimeters from the tiptop of their caput (crown) to the bottom of their buttocks (rump).

"This gives us the estimated gestational age," adds Dr. Celestine. Your health care provider can take these measurements betwixt weeks half dozen and seven of pregnancy up until week xiv. After week 14, your gestational age is determined past other methods (including measuring your baby's head circumference, abdomen, and thigh os). This is called biometry.

Your health intendance provider may compare your estimated due date based on your terminal period with any information from your first ultrasound. In the first few weeks after yous've constitute out you're pregnant, you may be given a couple of estimated due dates as your wellness care provider tries to institute the most authentic estimate. Brand sure that both y'all and your health intendance provider are using the same due appointment to keep track of your pregnancy.

Information technology'south important to remember that whether you're working from the first twenty-four hour period of your final period or the crown-rump length on an ultrasound, a due date is just a rough approximate of when the baby will come. "It tin can be off past a few days, either way," says Dr. Celestine. Most babies are born between 38 and 41 weeks of pregnancy. In one study of well-nigh xix,000 women in Australia, but five% of births really happened on their due dates. The due date is more of a guide to track how far along you are in your pregnancy than a set-in-stone borderline of when your babe volition arrive.

How long is a trimester, and why do we apply them to measure a pregnancy?

Well-nigh of us know that pregnancy is measured in three trimesters. Different symptoms and milestones are associated with each trimester. However, merely like the length of a pregnancy, at that place has been some confusion about how long each trimester lasts.

"People used to think trimesters are 12 weeks each, merely they're non — they're around 14," explains Dr. Celestine. "The commencement trimester goes to 13 weeks and vi days. The second trimester is from 14 weeks to 27 weeks and 6 days. And the tertiary trimester goes from 28 weeks to 42 weeks."

Equally mentioned higher up, a total-term pregnancy is one that is 39 to 40 weeks long. If you're withal meaning at 41 to 42 weeks, your health care provider will usually recommend an induction of labor.

Inducing labor is a medical procedure that helps your body get fix for and go into labor. A technique that is sometimes offered to help encourage labor is a membrane sweep.

Knowing which trimester you're in can give your medical professionals a framework for monitoring benchmarks in your baby's evolution and changes your torso is experiencing.

"Sure things happen at certain weeks," says Dr. Celestine. "The baby will exist hitting sure marks in terms of growth. Getting it relatively correct is important. If something seems a little bit off, we give it a bit of fourth dimension to recheck it again in guild to confirm if it'southward a true upshot or not."

If y'all're at all confused or concerned about what your health care provider is looking for at different points in your pregnancy, then reach out and ask questions. It'south so crucial that y'all feel supported and sympathize what is happening in your body and with your infant.

Are all pregnancies the same length?

It's important to recall that your estimated due date is but a rough guide, because non all pregnancies are the aforementioned length. Equally explained in a higher place, well-nigh pregnancies are around xl weeks long, but a baby tin safely get in at various points inside this time frame. There are a number of common terms that your wellness care provider may use to describe when your baby may arrive. They include:

Premature

A premature or preterm babe is a baby that'south born earlier 37 weeks. "So that's up to 36 weeks and 6 days," says Dr. Celestine. According to the Centers for Disease Control and Prevention (CDC), in 2020, x% of babies built-in in the United States were born preterm, then roughly one in 10.

If your babe is born preterm, they may need support from the neonatal or newborn intensive care unit (NICU) at your hospital. This could include help with breathing, regulating temperature, and feeding.

Early term

An early on term baby is ane that's born between 37 weeks and 38 weeks and half dozen days. "A baby born at 37 weeks might non have to be in the NICU and should be able to exhale on its own," says Dr. Celestine. "But it's even so what nosotros call early term." Some babies born at this gestational age practice have temporary breathing issues or may need extra help with breastfeeding, maintaining temperature, and managing carbohydrate levels.

Total term

A full-term baby is one that is born between 39 weeks, (the week before your due appointment), and xl weeks and 6 days. The CDC notes that 57% of all babies born in the United States in 2020 were full-term births. "If we're scheduling a cesarean section, we try to practise it in the 39th week," explains Dr. Celestine. "This is because nosotros attempt to exercise information technology before the woman goes into labor naturally."

Late term

A late-term infant is born from week 41 upwards to week 41 and vi days. In the United states of america, most OB-GYNs offer and recommend inducing labor between 41 weeks and 41 weeks and vi days. This is because at this point, the risks of standing the pregnancy increment. Dr. Celestine says, "We commonly induce labor if yous get to 41 weeks or beyond because at that betoken, the baby is safer out than in." However, it'due south important to remember that every pregnancy is different, and your wellness intendance provider may recommend inducing labor before 41 weeks if they think information technology'll be amend for y'all and your baby's health.

Post-term

A post-term babe is one born at week 42 and beyond. The most common reason for a baby to exist born postal service-term is because the initial estimated due date was calculated incorrectly.

What is the boilerplate pregnancy length for first-time parents?

While your due engagement may help you become a amend idea of how far forth in pregnancy you are, unless yous're having a planned C-section, information technology's impossible to know exactly when your baby will be born.

"Almost people evangelize betwixt 39 and 41 weeks," says Dr. Celestine. "Just statistically, first pregnancies are likely to be a little longer." Research into how long pregnancy is has varied. One assay highlighted that xv% of kickoff babies are likely to get in after 40 weeks, compared to 10% of subsequent babies. Nonetheless, the same report noted that 12% of offset babies were likely to be born earlier 37 weeks compared to 10% of other babies.

And so, it'south worth remembering that your due date may give you a general idea of when your baby will exist born, but there's no way to know for certain until the big mean solar day actually arrives.

What can impact the length of pregnancy?

If you've had a baby before, you may wonder if your second pregnancy and birth will be like to your first. One of the biggest factors in having a preterm birth is if you've had one before. If you gave birth before 37 weeks in a previous pregnancy, talk to your health intendance provider about actress monitoring or support to help lower your risk of having another preterm birth.

If you've had a baby who made a tardily arrival in the past, and so this tin also increase the chances that your electric current pregnancy volition go to full term or beyond.

Your commencement pregnancy doesn't always dictate what will happen next time.

Nevertheless, it's of import to remember that every pregnancy is unlike. "Your commencement pregnancy doesn't always dictate what will happen next time. If you take a change in a partner or a change of sperm donor, that can make a difference to gestation fourth dimension," says Dr. Celestine. 1 study notes that y'all could be at an increased risk of early birth or your baby having a lower nascence weight if you accept babies with two different partners. However, Dr. Celestine says, "Mainly, just as everybody is unique, every baby and pregnancy is unique."

One affair that will carry over from pregnancy to pregnancy, though, is run a risk factors for preterm birth. "If a pregnant person has a condition similar high claret force per unit area or diabetes, or avant-garde maternal age (if you're over the age of 35), then we'll need to take this into account across all their pregnancies," says Dr. Celestine.

How long is pregnancy: The takeaway
