You can use the photos below to learn what to look for during your own ultrasound or you can compare your photos to these images to see what your best guess is as to the sex of your baby. Remember, this is for fun and comparison, you should always ask questions of your doctor or midwife. Sometimes this lack of clarity has to do with the ultrasound equipment, the mother’s weight, the baby’s size…There are many factors involved in getting a clear picture from an ultrasound. The ultrasound technician has marked this one a girl as well. This image is more easily defined as you can see the baby’s thighs, too. These landmarks make it easier to tell what you are looking at, particularly when it is a photo and not a video. When you have your ultrasound done, remember that while the technician’s call is usually right, sometimes, mistakes happen. There are many reasons why your ultrasound might be wrong when it ​says girl or boy. These possible hiccups are usually controlled for in a variety of ways, but also you should have the limitations of your exam explained to you in a way that you can understand. Understanding the limitations of ultrasound technology will give you a better idea of how seriously you should take the results, and how much decorating you should do in the baby’s room or in a baby’s wardrobe.
