You'll notice that what you see varies a lot by the number of weeks of gestation. Each week in pregnancy can look slightly different. This can be due to the baby's development, the weight of the mother, the position of the baby, and the skill of the ultrasound technician, for example. 6:59 Everything to Know About Ultrasounds There are a lot of theories about what the ultrasound technician is looking for in a girl ultrasound.
