Sayang, at 39W4D without signs of labour is actually normal lah, some babies just take their time! But since you're so close to your due date, please check in with your doctor or midwife soon to make sure baby and you are doing okay, okay? A few of my mum friends who went overdue said their doctors monitored them closely, so jangan tunggu lama-lama. Walking, gentle movement, and staying calm membantu some of them, tapi setiap pregnancy is different. The best thing you can do right now is follow your doctor's advice, they'll know what's safest for you and baby. Dah arrange follow-up with your OB ke?
