Haha ada, a few of us memang kena kejutan macam tu! I have one friend whose scan showed boy tapi keluar girl, doc kata positioning baby macam tu je, so silhouette nampak confusing. Most accurate is around 18-20 weeks when features sudah clearer, tapi still ada margin of error especially kalau baby shy or position tertentu. I found out mine at 20 weeks and alhamdulillah betul, tapi honestly memang ada stories from other mums about the opposite happening too!
