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.
First babies are less likely to be “on time” at 39 weeks, and more likely to be a little late, between 41 and 43 weeks. Among full-term pregnancies, first babies are born about 1.3 days later on average. But the average doesn't tell the whole story.
On average for your first baby, the: first stage of labour can last from 10 to 14 hours. second stage of labour can take one to two hours to push your baby out. third stage can last five to 45 minutes.
Researchers now believe that when a baby is ready for life outside his mother's uterus, his body releases a tiny amount of a substance that signals the mother's hormones to begin labor (Condon, Jeyasuria, Faust, & Mendelson, 2004). In most cases, your labor will begin only when both your body and your baby are ready.
In one study… 81% having their first baby went past the due date. 61% of second, third or later pregnancies went past the due date. Fetal surveillance begins to be recommended.

Over time, the following notable changes were seen: an increase in the average age of first-time mothers (from 28.4 years in 2011 to 29.7 years in 2021) a decrease in smoking at any time during pregnancy (from 15% in 2009 to 8.7% in 2021)

More than 90% are born two weeks either side of the predicted date. But, as noted above, only 4% (or 4.4%, ignoring pregnancies with complications etc) are born on the predicted date itself - in other words, the chance of this happening is less than one in 20.

A DNA paternity test is nearly 100% accurate at determining whether a man is another person's biological father. DNA tests can use cheek swabs or blood tests. You must have the test done in a medical setting if you need results for legal reasons. Prenatal paternity tests can determine fatherhood during pregnancy.
About 60 out of 100 women give birth on or before their given due date. In another 35 out of 100 women, contractions start on their own within two weeks of the due date. But it takes longer in about 5 out of 100 women. The reason why the baby is overdue is usually not known.
