7 week of pregnancy ultrasound

The period between the sixth / seventh and the fourteenth week of pregnancy is the one in which the expectant mother usually undergoes the first ultrasound quarterly. Before the tenth week, however, it is very difficult to discern from the images an already defined shape of the embryo, which is still too small.

Already during the seventh week, however, the heart of the little one is already in full activity and pulses at a frenzied rhythm - more or less double that of the mother - and today's instruments can allow you to hear the forceful heartbeat.

Usually the first quarterly ultrasound provides the first essential information about the future baby:

  • gestational period
  • viability of the fetus
  • possible presence of twins
  • first anatomical evaluation of the fetus

Subsequent exams

The first trimester of pregnancy is crucial for the success of the pregnancy, therefore many control tests are concentrated during this phase of gestation.

In fact, after the first ultrasound, a pregnant woman can usually undergo:

  • Combined test exam: Also called duo test or bi-test, this is a screening test to reveal the presence of any chromosomal abnormalities (ex: down syndrome). It consists of two exams. The first is that of nuchal translucency, which measures a small layer of liquid that collects behind the nape of the fetus, while the second consists of a blood sample to calculate the concentration of two specific substances of pregnancy, human chorionic beta-gonadotropin ( beta-HCG) and pregnancy-associated plasma protein A (PAPP-A)
  • Coombs test: detects the possible presence of "antibodies to red blood cells" that could cause haemolysis (breakdown of red blood cells) in the fetus; An RH negative woman must repeat this test on a monthly basis throughout her pregnancy.
  • Complete blood count: check for anemia or platelet deficiency.

Based on the results of the ultrasound and the aforementioned examinations, further invasive tests such as CVS and amniocentesis may be necessary.

From the tenth week it is possible to carry out the fetal DNA test, a screening and non-diagnostic test such as amniocentesis and CVS, which allows to identify early the risk that the fetus is affected by chromosomal abnormalities.

Health tips in the seventh week of pregnancy

Nausea and vomit

For about half of women, the first period of pregnancy is characterized by the annoying appearance of nausea accompanied by vomiting, especially in the morning hours (but not only). Added to this is another 25 percent who are nauseated only.

Sometimes, nausea and vomiting are so important that they prevent both the normal performance of daily activities and the possibility for the mother to feed adequately (hyperemesis gravidarum): in such an eventuality hospitalization may be required, to ensure that the mother and baby do not suffer damage due to poor nutrition and hydration.

The causes of nausea are not well understood. The most suggestive hypothesis is that the disorder appears to prevent the expectant mother from eating foods that would not do her good: in fact, when you suffer from nausea you tend to follow a healthy diet, that is, with very little fat and lots of fruit and vegetables. .

The advices: eating little and often is the first rule: the ideal is to do five small meals a day. Some women feel relief from sucking one candy even before getting out of bed. Others rely on various remedies, such asacupuncture, the anti-nausea bracelets, which act by exerting a slight pressure on a point of the wrist indicated by traditional oriental medicine as ideal to remove the disorder, the consumption of tablets or herbal teas based on ginger, the consumption of cola-based beverages. however, although some patients claim to benefit from it, there is no scientific evidence regarding the effectiveness of such remedies.

Cosmetics and products for the beauty of body and hair

It is a classic doubt of pregnant women: can these products be used during the waiting months? In general yes, they are safe, as long as they are controlled origin and, therefore, compliant with CE regulations. Go ahead, therefore, for moisturizers, conditioners, beauty masks, nail polishes, eye shadows, lipsticks and mascara.

With regard to hair dyes, AIFA (Agenzia Del Paesena of the drug) underlines that studies carried out on humans have shown that absorption by the body is very limited, except in the case where there are wounds or abrasions on the scalp. As a result, it can be excluded that the substances contained in the tinctures can cause harm to the baby and you can dye your hair 3-4 times during pregnancy. Given this, for caution we recommend avoid doing this in the first trimester.

Tips: even if the cosmetics are considered safe, always as a precaution it is not recommended to use the products listed below, as there are not enough studies to guarantee their total harmlessness for the child. In fact, in the scientific field a "prudent use" is recommended, but it goes without saying that to be completely calm it may be better to avoid:

  1.  Retinoic acid e glycolic acid, mainly used in anti-acne products;
  2.  agents skin lighteners (to remove dark spots). Caution applies in particular to products containing hydroquinone;
  3.  creme anti-stretch marks. Use with caution (especially if they contain gotu kola, alpha-tocopherol and elastin hydrolysates), because the available data on the effects on our organism are still scarce;
  4. creme self-tanners, particularly if they contain dihydroxyacetone, because there are no studies on the effects of this substance in pregnancy;
  5.  Botox;
  6.  products insect repellents. Products based on Picardine and "PMD" (P-methane-3,8 diol) are preferable.

The danger of miscarriage

Since the embryo remains attached to the placenta, the loss of a pregnancy it is a danger that - albeit in minimal percentages - concerns the first thirteen weeks of pregnancy.

Obviously the presence of details health conditions (eg: obesity) or the repeated presence of harmful habits (e.g. smoking and alcohol in pregnancy or continuous excessive exertion) can contribute to increasing the chances of risk, but in most cases the most frequent causes of spontaneous abortion are chromosomal abnormalities o genetic of the fetus

The fetus in the seventh week of pregnancy

Having reached the seventh week, the head of the fetus - still similar in size to that of a large berry - is much larger than the rest of the body: a disproportion that will diminish over the weeks. The skeleton begins to form with the development of tissues that will become the spine and other bones, while the heart continues to grow, beating at a regular rate.

In this era, the presence of the baby is not perceptible from the outside (the baby bump has not yet delineated), nor can you feel its movements.
