Gender scan

I jumpa specialist di hospital swasta. My first pregnancy, around 20w during detail structure scan my doctor confirm baby girl. Then my second pregnancy at 16w Dr bagitau 99% gender dia boy but since genital masih developing that time dia cakap tunggu next scan lagi. Scan lagi on 19w for detail scan, confirm sudah baby boy. Sy rasa kalau mampu better jumpa Specialist or pergi hospital yang ada better facility supaya scan machine can detect better and dorang punya skill scan baby pun lagi bagus. Kalau doctor tu ragu2 or tidak sure, macam bazir duit saja scan di random clinic balik2.
