Walaupun doc confuse, honestly susah la nak predict 100% akurat dari ultrasound alone, a few of us tried guessing based on nub theory and all that, tapi half the time kena balik! Best way is wait for the anatomy scan atau kalau ada NIPT test boleh confirm through DNA, tapi honestly the excitement of the surprise tu yang best. Kalau doc sendiri unsure, maybe tanya dia ulit lagi around 20 weeks when baby position lagi clear?
