Girl or boy?

Saya pergi routine checkup 16 weeks, masa scan my doctor cakap mungkin boy. Then schedule detail scan at 20 weeks, doctor confirm girl. Saya tak puas hati so saya try gender scan clinic lain dgn sonographer nampak la penis dgn scrotum. Memang benda ni normal ke terjadi tiba2 tak nampak penis bila scan and mistaken as girl? Apa pengalaman korg ya? #firstbaby #firstmom
