What is a key indicator of a pregnancy that is considered post-term?

A key indicator of a pregnancy that is considered post-term is a birth after 42 weeks of gestation. Post-term pregnancy, also known as prolonged pregnancy, occurs when the pregnancy extends beyond 42 weeks.

This classification is important because pregnancies that last longer than this period can pose increased risks for both the mother and the baby, including complications like placental insufficiency, meconium aspiration, and increased likelihood of cesarean delivery.

In contrast, a birth before 37 weeks is classified as preterm, while a birth at 38 weeks or 41 weeks falls within the normal term range. Thus, birth after 42 weeks is the defining factor for post-term pregnancy.
