26 week ultrasound

Im just curious have any of you ladies had to have more ultrasounds than the normal amount because of a stubborn baby? This is my second ultrasound within a 6week period and I was just wondering if its just because of how my son is positioned and refuses to move so the tech can get his organ measurments or just because different hospitals have different procedures. With my first I only had 5 the whole time I was pregnant but that was at a different practice and different doctor. Thanks in advance. This is my baby's face, the only good picture she could get of him too.
