Your due date passed. What now?

Most first-time parents arrive at their due date expecting a baby, and instead continue to be pregnant. This is normal — only about 4% of babies are born on their exact due date. Going a few days or even a week past is common, especially with first pregnancies.

What "overdue" actually means

A pregnancy is considered post-term at 42 weeks. Between 40 and 42 weeks, you're technically past your due date but not yet post-term — this period is often described as "late term" (41 weeks) or simply overdue. Most providers begin more frequent monitoring from 41 weeks, and induction is usually recommended by 42 weeks.

Why does this timing matter medically? Placental function can decrease as pregnancy extends beyond 40 weeks, potentially reducing oxygen and nutrient delivery to the baby. The amniotic fluid level also tends to decrease. These changes increase the risk of complications, which is why monitoring and eventually induction are part of the management plan.

Monitoring post-dates

From around 41 weeks, most providers offer more frequent check-ins, typically twice-weekly non-stress tests (monitoring the baby's heart rate and movements) and ultrasound assessments of amniotic fluid levels. These tests help identify whether the baby is tolerating the continued pregnancy well.

If monitoring shows any concerns — reduced fluid, concerning heart rate patterns, or reduced fetal movement — induction becomes more urgent regardless of gestation.

Induction

Induction means using medical interventions to start labour artificially. Methods include a membrane sweep (where a midwife manually separates the amniotic membranes from the cervix, stimulating prostaglandin release), prostaglandin gels or pessaries to ripen the cervix, artificial rupture of membranes, and oxytocin (pitocin) drip to stimulate contractions.

Induction often takes longer than spontaneous labour, and the experience can be more intense. Having realistic expectations about the timeline — induction can take 24–48 hours from start to active labour — is important for managing it.

Research from the past several years (including a large US trial called the ARRIVE trial) suggests that elective induction at 39 weeks doesn't increase caesarean rates and may reduce some risks compared to expectant management. Many guidelines have shifted as a result, and induction is now offered earlier in some healthcare systems than it previously was.

What you can do while waiting

Some methods people try to encourage labour naturally — walking, eating dates, pineapple, nipple stimulation, sex — have varying levels of evidence. Nipple stimulation does cause oxytocin release and may help in some cases; the evidence for the others is weak. They're unlikely to hurt, but expectations should be realistic.

More usefully: rest while you can. Make sure your hospital bag is packed. Know the signs of labour (regular contractions increasing in frequency and intensity, waters breaking) and when your provider wants you to call them or come in.

Being overdue is frustrating. Every day feels long when you're at the end of pregnancy and waiting. But most babies born after 40 weeks are completely healthy, and labour typically starts on its own well before 42 weeks.
