What will ultrasound show at 7 weeks of pregnancy?
This study is conducted to confirm possible genetic abnormalities. In this case, the doctor very carefully examines the fetal egg, to exclude that it is empty.
In addition, they establish the size of the embryo, make an overall assessment of its development. The bones of the skull and the spine are clearly visible.
Determining the sex of the baby at this time is simply impossible, because there is still no difference between the genitals. In their place there are sexual tubercles, which are only the germs of the reproductive system.
What happens to the embryo at 7 weeks?
Ultrasound on the 7th obstetric week of pregnancy shows that the size of the unborn child at this time is still very small. Quite often, doctors compare it with wheat grain.
However, despite this, the heart is already actively working and produces up to 200 cuts per minute. The brain continues to develop rapidly. It should be noted that this process is proceeding at a reactive rate: in one minute up to 100 nerve cells can be laid.
Formed, the so-called protrusions on the body of the embryo, which in fact are the beginnings of the limbs of the future baby. There is a differentiation of the upper humeral girdle: the bones of the shoulder and forearm are formed.
At this time, the oral cavity and the language of the future baby are formed. Despite this, all the nutrients he will receive before birth through the umbilical cord from his mother.
At 7 weeks, the kidneys of the future baby are made up of 3 parts, and literally within a week they will start producing urine, which will flow directly into the amniotic fluid.
How are ultrasound done at week 7?
Due to the fact that the size of the embryo at this time is very small, the procedure involves transvaginal access. In this case, the sensor from the ultrasound machine is inserted directly into the vagina. This allows us to evaluate not only the fetus itself, but also to examine the uterus, to establish its dimensions.
The procedure is performed in the supine position. Its duration is of the order of 10-15 minutes.
