The second ultrasound takes place at the end of the 5th month of pregnancy and is called the "anatomy ultrasound".
For the 2nd ultrasound, you are more relaxed.
The midwife or obstetrician checks the spine, the kidneys, and the stomach, but especially they check if the heart has formed. You will discover if it is a boy or a girl.
But you might want to keep it a surprise!
