When is the first pregnancy ultrasound performed?

Last Update: 10/30/2025

The first ultrasound usually takes place during the first trimester of pregnancy. It is typically performed between weeks 6 and 12 to confirm the pregnancy.

The later it is done, the more information it provides. The purpose of this first gestational ultrasound is to observe the gestational sac and assess whether the embryo is implanted in the correct location or, conversely, if an ectopic pregnancy has occurred.
