10 things to know about Post-Term Pregnancy
- Normal pregnancy last between 37 weeks to 42 weeks. The estimated due date is 40 weeks or 280 days from the first day of your last menstrual period.
- Post-term (or prolonged) pregnancy last longer than 42 weeks and occurs in 10% of pregnancies. However, most obstetrical providers advise deliveries by 41 weeks.
- Accurate dating is important in the diagnosis of post-term pregnancy. Ultrasound before 24 weeks can accurately date the pregnancy.

- Stillbirth or infant death near time of birth (4-7/1000 deliveries) increases after 40 weeks and doubles after 42 weeks gestation
- Birth trauma with difficulty delivering shoulders (shoulder dystocia) which may result in nerve injuries
- “Post maturity syndrome” with intrauterine growth restriction or insufficient growth of the baby, decreased amniotic fluid with increased risk of cord compression, and long term neurological defects
- meconium aspiration, baby inhaling bowel content resulting in breathing problems
