Ahhh I understand, sometimes baby shy la kan! Honestly at 24 weeks the angle and position really memang affect whether doc boleh see clearly or not, kalau baby sitting in certain way, memang susah nak confirm. A few of us tried the "walk around, change position" trick before scan nak help baby move, or go back for another scan at 26-28 weeks when baby dah bigger sikit, usually clearer! If you really curious before that, boleh ask doc to try 3D scan next time, sometimes clearer for gender spotting. But tak pe, another 2-4 weeks and baby dah jadi clearer, then confirm sure boleh tengok!
