The 21st week of pregnancy – is a term of the planned ultrasound examination. Ultrasound is necessary to check how is the child developing and growing, whether the size of the internal organs corresponds to the size of a body on this gestational age, to find out the state of the placenta and amniotic fluid, and it is a great opportunity to find out the gender of the baby, if future parents still did not have such a possibility.

The heart of the future baby is exposed to special thorough investigation during the 21th week of pregnancy. If the gynecologist of the antenatal clinic suggests pathology in heart development, he would send a pregnant woman to additional research, as heart disease is now one of the most common pathologies.

Also, the expectant mother will need to pass a general analysis of urine and blood.
