A 2D ultrasound can be made throughout the duration of your pregnancy and is a nice way to enjoy a look at your child. The ultrasound takes approximately 15 minutes and you will receive a USB stick and of course a few pictures to take home.
2D ultrasounds are black/white images where you see cross-sections of the child and it seems like you can “look inside” the child. You see the baby lying and moving in the amniotic fluid. You are also usually able to see details such as the profile and hands and feet. You are able to make nice 2D images until far along in the pregnancy.
