At nine months, an AFI of 4.0 indicates low amniotic fluid, and signs of fetal hypoxia (low oxygen) require prompt medical attention. Your obstetrician will likely recommend immediate hospital admission for close monitoring. While a vaginal delivery is sometimes attempted under continuous fetal monitoring, the combination of hypoxia, low fluid, and a cord around the neck makes labor riskier for the baby. Therefore, a Cesarean section (C-section) is usually the safest and most recommended route to ensure a quick and safe delivery. Please contact your doctor or proceed to your maternity hospital immediately so the medical team can safely guide your next steps.
