Most pregnancies last 37 to 42 weeks, but some take longer. If your pregnancy lasts more than 42 weeks, it is called post-term (past due). This happens in a small number of pregnancies. While there are some risks in a post-term pregnancy, most post-term babies are born healthy.
The longest pregnancy ever recorded was 375 days long (17 months). In comparison most women are pregnant for 280 days.
You are more likely to be overdue if you are obese, have never given birth before or if you're over the age of 30. Your midwife or doctor will check that both you and your baby are healthy by giving you ultrasound scans and checking your baby's movement and heartbeat.
There's a higher risk of stillbirth if you go over 42 weeks pregnant, although most babies remain healthy. At the moment, there's no way to reliably predict which babies are at increased risk of stillbirth, so induction is offered if you do not go into labour by 42 weeks.
When a pregnancy reaches 42 weeks and beyond, it's postterm. Late-term and postterm pregnancy can raise the risk of some health problems, including: Larger than average birth size (fetal macrosomia). This increases the chance that you may need forceps, a vacuum device or another instrument to assist with the birth.
Most overdue pregnancies do just fine, with no complications for moms or their babies. An overdue baby may look a little different, though. Past-due babies can have relatively long and thin arms or legs, dry or peeling skin, and longer hair and nails than younger babies. They're often very alert at birth, too.

But maybe these claims are not so odd when you remember that the average pregnancy is actually nearer 10 months than nine. So if you give birth at 43 weeks, you are heading towards 11 months anyway.
After studying the data of various moms and their birth dates, researchers found a connection between high stress events and women having longer-than-expected pregnancies. Pregnant women that were 33-36 weeks along on September 11, 2001 were found to have more post-term pregnancies than expected.
Full-term pregnancies typically last from 39 to 41 weeks, but it is also not uncommon for a baby to come slightly before or after that timeframe. In fact, studies show that fewer than 5% of women deliver on their due date and only 70% give birth within 10 days of their due date.
(Reuters Health) – Children born in the 41st week of pregnancy – which is considered “late-term” - have better test scores and are more likely to be classified as gifted in elementary and middle school, compared with children born “full-term,” that is, at 39 or 40 weeks.
About 60 percent of women will give birth on or before their due date. Only about 1 in 10 babies is officially overdue or born beyond 42 weeks of pregnancy though. Based on these statistics, you may be wondering how to calculate your due date and what factors might contribute to having an overdue baby.
However, from the current medical evidence, most medical authorities do state that if multiple C-sections are planned, the expert recommendation is to adhere to the maximum number of three.”
According to research, a woman can have somewhere around 15 to 30 babies in her lifetime.
You should discuss this with both your doctor and midwife so that together an appropriate plan of care can be made. This plan will include increased antenatal assessments. If your pregnancy continues past 41 weeks and 3 days, your midwife will recommend you attend hospital for a biophysical profile.
Mothers may also be more likely to deliver late if overdue pregnancies run in the family. “Family history of overdue pregnancies is a stronger predictor than whether or not it is a first-time mother,” said Dr.
A woman's peak reproductive years are between the late teens and late 20s. By age 30, fertility (the ability to get pregnant) starts to decline. This decline becomes more rapid once you reach your mid-30s. By 45, fertility has declined so much that getting pregnant naturally is unlikely for most women.
Pregnancy is counted from the first day of your last menstrual period. This means an extra 2 weeks are counted at the beginning of your pregnancy when you aren't actually pregnant. So pregnancy lasts 10 months (40 weeks)—not 9 months—because of these extra weeks.
Book a special massage or pedicure to give yourself something to look forward to and take your mind off all the waiting. Don't take all the old wive's tales too seriously. Pregnancy is exhausting and sleep can be hard to get. Grab any opportunity to sleep away the waiting with both hands.
The researchers found that 50% of all women giving birth for the first time gave birth by 40 weeks and 5 days, while 75% gave birth by 41 weeks and 2 days. Meanwhile, 50% of all women who had given birth at least once before gave birth by 40 weeks and 3 days, while 75% gave birth by 41 weeks.
But if the pregnancy is overdue, the soon-to-be parents may be expecting a son. Studies have found that boys not only produce longer pregnancies, but also longer labors. The apparent reason for the extra duration is that boys are typically heavier and larger than their female counterparts.
