Are first babies usually late or early?
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.
How accurate are due dates for first babies?

What week of pregnancy are most first babies born?
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.
Why do some babies come late?
The reason why the baby is overdue is usually not known. Sometimes it is because of a genetic predisposition (hereditary). Women who have already had a baby that came much later than their due date are more likely to have an overdue baby in future pregnancies. Being born after the 40th week only rarely harms the child.

In 2017, 73 percent of babies were born before their due dates. Two decades earlier, in 1997, that figure was 57 percent. That difference is partly because inductions and cesarean births have become more common, but also because methods for estimating due dates have improved.
