One of the most common procedures for the control of pregnancy is ultrasound, during pregnancy three are essential, although some authors speak of four important.

During the first trimester it is essential to do at least one, more or less at 12 weeks gestation.

1. In early pregnancy, it serves to confirm pregnancy and accurately calculate gestational age (not always done).

2. At 12 weeks, to know, among other things, the nuchal translucency.

3. At week 20, known as morphological ultrasound.

4. And at the end of pregnancy around week 32-35, to confirm the normal growth of the baby.

However, many women who follow the pregnancy with a private gynecologist can have an ultrasound at each visit, not because it is necessary, but because it tends to excite future parents. In fact, many women get an ultrasound every month.

In most private gynecological centers, an ultrasound is done every month. The first is the one that confirms the pregnancy, and basically serves to verify that there is a gestational sac. This is done around 6 weeks of gestation.

The second ultrasound certifies that it is not an ectopic pregnancy. The baby's heart is clearly heard and it is verified that the pregnancy continues correctly. It is done around 9 weeks of gestation.

The most important is undoubtedly the 12-week ultrasound. In it, a lot of information is obtained since at this time the anatomical development and the size of the fetus allow us to verify that most of the organs have formed properly.

A high-level ultrasound at this time can detect up to 60-70% of possible malformation problems that will appear in pregnancy. The other measurement that is made is the nuchal translucency, the liquid that all fetuses have in the neck. It is also called the nuchal fold.

The thickness of the nape of the fetus can be measured and its value is used as part of the first trimester screening (or screening). This screening allows estimating the risk of having an abnormality in the number of chromosomes (technically defined as aneuploidies), especially trisomy 21 or Down syndrome. To calculate the risk, the value of the nuchal translucency is combined with the maternal age, and the values ​​of two hormones (beta-HCG and PAPP-A) that have been carried out in blood tests.

This ultrasound for the parents is very exciting, since their future child is already having a shape more or less similar to a baby, he moves (often too much!) Although the mother still does not perceive it, and sometimes the obstetrician is already capable of tell them what sex their child will have (although most of the time we prefer to wait until week 20, since in that ultrasound the sex is already well in sight). It is many times as a result of this test that parents are aware that they are really going to be parents, everything materializes a lot. Especially in those cases in which the pregnancy passes without symptoms.
