When is it best to have an ultrasound during pregnancy? The timing of the ultrasound examination will depend on the information you want. Already in week 6, ultrasound can confirm that there is a beating heart, how many fetuses there are, whether embryos are in the uterus and the length of the pregnancy. But we recommend an early ultrasound from week 7.
