Haha, the burger shape! Honestly sis, gender scans can be tricky especially if baby positioning tak cooperate, a few of us from my mum group had the opposite happen (thought girl, turned out boy), so it really depends on the angle and how clear the view is at that moment. If doktor confidently said boy tapi you're getting that doubt feeling, boleh always ask for confirmation scan next time or maybe get a second opinion from another sonographer just to be sure, because honestly, these things happen more often than you'd think!
