Late pregnancy monitoring

Pregnancy is considered to be prolonged when it has lasted over 42 gestational weeks. Postterm check-ups start when the pregnancy has lasted 41 weeks and 5 days (41+5). You must book an appointment for the postterm check-up yourself by calling the maternity hospital’s unit for induction of labor or maternity outpatient clinic.

Usually we can calmly wait for the labor to begin naturally. The aim of the postterm check-ups is to monitor that the final stage of the pregnancy proceeds safely, and to detect early any risks related to a prolonged pregnancy (e.g. placental deterioration).

Both the mother and fetus's well-being are monitored at the postterm check-up. Fetal condition is assessed by recording the fetal heartbeat (CTG) and via ultrasound examination. The mother’s blood pressure is measured and proteinuria is ruled out. The appointment also includes a discussion with the mother regarding her physical and psychological well-being and coping and how the mother feels the fetal movements.

Sometimes at the postterm check-up, a process called cervical canal ripening may be started either mechanically or by pharmaceutical methods. If mechanical cervical ripening, with a balloon catheter, is started, the mother may still usually return home, but if pharmaceutical cervical ripening is started, the mother will remain in the hospital. Labor is induced due to a prolonged pregnancy by gestational week 42+1 at the latest.
