Eligibility Criteria

Female participants from 14 years up to 45 years old.

Inclusion Criteria: 1. Women with any breech presentation 2. A live singleton fetus 3. Gestational age of 33 weeks 0 days to 35 weeks 6 days Exclusion Criteria: 1. Contraindications to ECV (e.g. fetal heart rate abnormalities, abruptio placenta, major life-threatening fetal anomalies, uterine anomalies, hyper-extended fetal head, rupture of membranes, severe oligohydramnios, severe polyhydramnios) 2. Contraindications to early ECV (e.g. increased risk of preterm labour [such as past history of preterm labour in this or previous pregnancies], increased risk of abruptio placenta [such as maternal hypertension]) 3. Contraindications to labour or vaginal delivery (e.g. placenta previa, previous classical CS) 4. Women planning delivery by CS if the fetus turns to cephalic 5. Women planning a vaginal delivery if the fetus remains breech 6. Women at increased risk of unstable lie (eg. grand multiparity) 7. Previous participation in EECV2 Trial
