You\u2019re pregnant, and now you\u2019re looking forward to welcoming a baby in a few months. But now the question is\u2026when, exactly, can you expect that little bundle of joy to arrive?\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">A typical pregnancy is approximately<\/span> <a href=\"https:\/\/www.hopkinsmedicine.org\/health\/wellness-and-prevention\/calculating-a-due-date\" target=\"_blank\" rel=\"noopener\"><span style=\"font-weight: 400;\">280 days<\/span><\/a><span style=\"font-weight: 400;\">, or 40 weeks, according to Johns Hopkins Medicine. Of course, that can vary from woman to woman. A pregnancy is considered full term when you have reached the 39-week mark but haven\u2019t hit the 41-week mark yet. Unless there are complicating factors, your obstetrician or nurse midwife will want you to hit that mark before delivering because it\u2019s best for your baby. If it looks like your baby is going to be born early, you may need to undergo steroid injections to help make sure the baby\u2019s lungs are ready.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">\u201cThe frequency of adverse neonatal outcomes is lowest among uncomplicated pregnancies delivered between 39 0\/7 weeks of gestation and 40 6\/7 weeks of gestation,\u201d the American College of Obstetricians and Gynecologists (ACOG) <\/span><a href=\"https:\/\/www.acog.org\/clinical\/clinical-guidance\/committee-opinion\/articles\/2013\/11\/definition-of-term-pregnancy\" target=\"_blank\" rel=\"noopener\"><span style=\"font-weight: 400;\">reports<\/span><\/a><span style=\"font-weight: 400;\">.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Plus, your due date (also called an estimated date of delivery or EDD) can help shape the prenatal care you receive. \u201cThe reason due dates are so important is because testing or treatment may need to be done at a certain gestation,\u201d explains <\/span><a href=\"https:\/\/mynursing.msu.edu\/s\/1393\/05-alumni\/16\/main-container-sidebar-navigation.aspx?sid=1393&amp;gid=2&amp;pgid=5523\" target=\"_blank\" rel=\"noopener\"><span style=\"font-weight: 400;\">Judith Strunk<\/span><\/a><span style=\"font-weight: 400;\">, DNP, MSN, a family nurse practitioner and assistant professor for the Michigan State University College of Nursing.

And there are three different dates that you can use to calculate your estimated due date:\u00a0<\/span><\/p>\n<ol>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Your last menstrual period, which is determined by your first day of bleeding<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">The date you actually conceived<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">The day that your embryo transfer occurred if you\u2019re using in vitro fertilization to conceive<\/span><\/li>\n<\/ol>\n<p><span style=\"font-weight: 400;\">Let\u2019s look at each one of those dates in more detail.\u00a0<\/span><\/p>\n<h3><span style=\"font-weight: 400;\">Your last menstrual period<\/span><\/h3>\n<p><span style=\"font-weight: 400;\">If you go this route, you\u2019ll use the first day of your last menstrual period (lmp) as Day 1. You could essentially count forward until you reach Day 280, and that would be your due date. Or you could employ a three-step method known as Naegele\u2019s Rule. You count backward three months from the date of your last menstrual period and then add seven days and one year. Pregnancy tests are most reliable starting the day of your missed period. By that point, you\u2019d be about four weeks pregnant. But it\u2019s important to note that <\/span><span style=\"font-weight: 400;\">Naegele&#8217;s rule is considered a guideline for the expected due date\u2014it does not provide a definite date.<\/span><\/p>\n<h3><span style=\"font-weight: 400;\">The date of conception\u00a0<\/span><\/h3>\n<p><span style=\"font-weight: 400;\">If you\u2019re tracking your ovulation and you\u2019re confident in the exact day that you got pregnant, you could calculate your due date from this date. Just <\/span><a href=\"https:\/\/my.clevelandclinic.org\/health\/diagnostics\/22052-due-date-calculator\" target=\"_blank\" rel=\"noopener\"><span style=\"font-weight: 400;\">count ahead 38 weeks<\/span><\/a><span style=\"font-weight: 400;\">, suggests the Cleveland Clinic. This assumes, however, that you know exactly when you ovulated and when you conceived.\u00a0<\/span><\/p>\n<h3><span style=\"font-weight: 400;\">Your IVF transfer date\u00a0<\/span><\/h3>\n<p><span style=\"font-weight: 400;\">During IVF, your provider will retrieve your eggs, create embryos, then transfer the embryos into your uterus. Day 1 will depend on how many days after your egg retrieval that the embryo transfer occurs on.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">In other words, you may have a standard 28-day cycle, or you might not. You might ovulate exactly two weeks after the first day of your period, but you might not. And since your menstrual cycle may vary, that can affect your due date.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">An ultrasound scan (or sonogram) can also provide some useful info and even shed a little more light on the gestational age. But the earlier that you get an ultrasound, the better, says Dr. Hoffman. That is, the closer to actual conception, the more accurate the ultrasound will be. \u201cWe usually do a sonogram at the first visit,\u201d Dr. Hoffman says. \u201cUsually we see people at seven, eight or nine weeks, or sometimes six weeks.\u201d<\/span><\/p>\n<h2 id=\"accuracy\">How accurate is my due date? Can it change?<\/h2>\n<p><span style=\"font-weight: 400;\">Just remember: Don\u2019t get too attached to a specific due date. \u201cRarely do babies come on their due dates,\u201d says <\/span><a href=\"https:\/\/www.cumedicine.us\/providers\/college-of-nursing\/jessica-anderson\" target=\"_blank\" rel=\"noopener\"><span style=\"font-weight: 400;\">Jessica Anderson, DNP<\/span><\/a><span style=\"font-weight: 400;\">, the director of midwifery services and associate professor with the University of Colorado Anschutz Medical Campus. \u201cThat\u2019s rare. It happens, but it\u2019s not the most common or likely thing that\u2019s going to happen.\u201d<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Your due date is only an estimate. That is, you can get pretty close, but very few babies are actually born on their due dates. It is definitely possible, of course, says Dr. Hoffman, but there\u2019s a lot of variability at work. \u201cA due date is only as good as the information going into calculating it,\u201d Strunk reiterates.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">One reason why your due date may not match up with the date that you actually deliver: A textbook pregnancy might be 40 weeks, but not everyone delivers right on the 40-week mark. Some people deliver earlier, and some people deliver later.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Plus, 40 weeks is just the estimate for the end of a singleton pregnancy. Twin pregnancies tend to end sooner, with many twin deliveries occurring around the <\/span><a href=\"https:\/\/www.hopkinsmedicine.org\/health\/conditions-and-diseases\/staying-healthy-during-pregnancy\/twin-pregnancy-answers-from-maternal-fetal-medicine-specialist\" target=\"_blank\" rel=\"noopener\"><span style=\"font-weight: 400;\">36-week mark<\/span><\/a><span style=\"font-weight: 400;\">, according to Johns Hopkins Medicine. And triplets tend to arrive even sooner. The American Society for Reproductive Medicine suggests that <\/span><a href=\"https:\/\/www.reproductivefacts.org\/news-and-publications\/patient-fact-sheets-and-booklets\/documents\/fact-sheets-and-info-booklets\/multiple-pregnancy-and-birth-twins-triplets-and-high-order-multiples-booklet\/\" target=\"_blank\" rel=\"noopener\"><span style=\"font-weight: 400;\">32 weeks<\/span><\/a><span style=\"font-weight: 400;\"> is the average gestational age of triplets at the time of delivery.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Once you\u2019re given a due date, could it change? Maybe, says Strunk. \u201cIt may change if there is more than a week discrepancy with a due date calculated from measurements taken during a first trimester ultrasound,\u201d she says. Your due date may adjust, depending on factors such as how early you get an ultrasound and how many babies you\u2019re carrying. (Dr. Hoffman says that first babies also tend to be born later.) So don\u2019t get too attached to that due date until you have more information from your healthcare provider.\u00a0<\/span><\/p>\n<h2 id=\"planning\">Can I plan my due date?<\/h2>\n<p><span style=\"font-weight: 400;\">Some people are planners by nature, which extends to the desire to plan a pregnancy and delivery. They may want to aim for a delivery in a particular season or month, or they may want to avoid having a new baby at a particular time. For example, you may dread the idea of being pregnant during a long, hot summer. Or you might like to avoid having a baby during a month when many of your other family members already have birthdays. It\u2019s a good idea to talk with your healthcare provider in advance if you have specific timelines for pregnancy and delivery.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">As already noted, due dates are estimates. But you can give yourself a better chance at achieving a due date in your desired range by tracking your period to find out when you\u2019re <\/span><a href=\"https:\/\/www.singlecare.com\/blog\/ovulation-guide\/\"><span style=\"font-weight: 400;\">ovulating<\/span><\/a><span style=\"font-weight: 400;\">. Among other methods, some women opt to use <\/span><a href=\"https:\/\/www.singlecare.com\/prescription\/clearblue-digital-ovulation\"><span style=\"font-weight: 400;\">ovulation predictor kits<\/span><\/a><span style=\"font-weight: 400;\"> to detect luteinizing hormone in their urine. A rise in this hormone signals that ovulation is imminent. Once you have a good handle on your ovulatory time, you can plan sexual intercourse to coincide. And hopefully, you\u2019ll get lucky.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">But if not, don\u2019t panic, especially if you\u2019re just getting started with trying to get pregnant and you don\u2019t have any complicating health issues that you\u2019re aware of. \u201cSometimes it\u2019s normal for it to take three to six or eight months to conceive,\u201d Anderson says.\u00a0<\/span><\/p>\n<h2 id=\"how-many-weeks\">How many weeks pregnant am I?<\/h2>\n<p><span style=\"font-weight: 400;\">As you probably know by now, pregnancy is counted in weeks, rather than months. (Except for the people who stop to pepper you with questions about your baby bump in the grocery store.)\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Every pregnancy is divided into <\/span><a href=\"https:\/\/kidshealth.org\/en\/parents\/pregnancy-calendar-intro.html\" target=\"_blank\" rel=\"noopener\"><span style=\"font-weight: 400;\">three equal parts called trimesters<\/span><\/a><span style=\"font-weight: 400;\">:<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">The first trimester is week 1 through the end of week 12<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">The second trimester is week 13 though the end of week 26<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">The third trimester is week 27 to the end of the pregnancy\u00a0<\/span><\/li>\n<\/ul>\n<p><span style=\"font-weight: 400;\">You can probably expect certain milestones to occur during each trimester. For example, many women experience nausea and vomiting during the first trimester. Those symptoms fade for some women when the second trimester rolls around, and they start to feel a little more energetic. Second trimester is also when most women begin to notice little fluttery movements\u2013signs that yes, there\u2019s actually a baby in there. Your doctor may also perform an anatomy scan around 20 weeks of pregnancy during the second trimester, and you can find out your baby\u2019s sex.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">When the third trimester gets underway, your due date will probably loom large in your mind, as you may start the countdown toward delivery and meeting your new baby. Your provider will want to monitor you more closely as your due date approaches, in case any interventions need to happen. That due date will come in handy for making those types of decisions.\u00a0<\/span><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Due date calculator | How to calculate due date | Accuracy | Planning | How many weeks pregnant am I?
