Exacerbation of smell and taste during pregnancy for 3 weeks Tips in pregnancy calendar on Babyblog. U.

, are able to determine if the smell is pregnant, whether the female is pregnant. The new work of biologists provides the first evidence that pregnancy at primates is really associated with a defined "aroma". At the same time, future mothers who carry boys and girls smell in different ways.

Scientists took for experiment 12 females using cotton swabs collected samples of secretions before and during pregnancy of animals. Then they conducted a chemical analysis that allowed to allocate hundreds of ingredients that are part of the "perfume of pregnancy" lemurs.

An unexpected discovery was the fact that the chemical composition of the selection of females before pregnancy was much more complicated than that of future mothers. And these changes were more pronounced when Lemurs wore sons in the womb. Also, scientists have discovered that changes in the composition of the selection correlate with the content of hormones in the blood.

A more diverse chemical composition of the selection of females, pregnant sons, researchers are explained by the fact that, perhaps, males who are in the womb, are a parent of large energy costs.

Scientists also note that the ability of males to identify the pregnancy of females in the smell is peculiar to the species inadvertible in sexual relations. And lemurs and people are suitable for this category. According to scientists, in the case of animals "smell of pregnancy" helps to resolve social interactions within groups of individuals.

"This feature is a big advantage for males, as they, as well as the mother, get the opportunity to find out in advance that they will become a parent. As for various smells in sons and daughters, we suspect that we suspect that They help future parents to prepare for various social responsibilities, "Crawford explains.

Man This ability could be "inherited" (however, it is also to be determined). Crawford and his colleagues are planning to carry out similar studies on other primates genetically closer to Homo Sapiens.

Pregnant women in 80-90% of cases transfer coronavirus infection in light or medium-free forms, TASS told the director of the institute of obstetric NMITs of obstetrics, gynecology and perinatology. Academician V. I. Kulakova, Professor Ran Roman Shmakov.

"Pregnant women carry an infection in a light or medium-free form, up to 80-90% of cases. Pregnant women are all classic symptoms: high temperature, dry cough, loss of smell. In this case, there may be adverse outcomes of pregnancy - there are losses Pregnancy, there are premature genera, the preeclampsia (pathology) happens, so they need to be very followed by them. However, future mothers carry the disease easier than the elderly. Newborn does not hurt, they simply transfer this virus, "he said.

The expert noted that in Russia they are based on the Chinese approach of guide in the presence of coronavirus disease - the newborn immediately divide with the mother until its torque tests do not show negative results. The newborn is also conducted tests for the presence of infection - immediately at birth and on the third day.

"We [in the center] passed about 30 births here with such patients. We immediately cross the baby with the umbilical cord and transfer to the children's table, which is at a distance of more than two meters, where the newborn is processed. Then We put it in the children's office, the "green zone". Not a single child has a positive covid, "the director of the institute of obstetrics shared.

reported two cases of birth of children from women with coronavirus disease, which also confirmed the presence of coronavirus - in North Ossetia and Saratov. "In the publications that I read in the media is not specified, whether the mother with the child was held together immediately after birth or how much the newborn isolation was correct. I can not comment on specific cases, but according to literature, which was available to me, is described in the world only Two cases of virus transmission newborn, but whether this vertical transmission from mother to a child or infection occurred after birth, it is difficult to say. All studies of the accumulating waters, the vagina during childbirth showed that in principle these environments are negative, that is, there is no coronavirus there. Hypothetically, the virus is not vertically transmitted, "said Shmakov.

"I infected, as it seems to me, from her husband. He came from the next fees at night, and the temperature rose in the morning. I immediately realized that something was wrong, quickly gathered and left for mom. We stayed together just six hours, but apparently, I still managed to get infected.

Ten days disappeared after ten days. I did the test - and he is positive. No more symptoms were: neither cough, no temperature. Even the smells returned in four days. But still, at first there was a feeling that the world collapses. After all, I went to the 40th week of pregnancy .

What to do? Scream-squeak and beat your head against the wall - meaningless. I still had no options. This pandemic turned upside down not only my plans, but almost the whole world. So I tried to accept and calm down, so as not to harm my son.

The third week of pregnancy is and there is a period of conception. If you count the pregnancy in obstetric periods, the third week will have the most ovulation, in which the desired conception occurs.

Gynecologists' obstetricists are accustomed to count the pregnancy from the first week of the last month. As you understand, no real pregnancy at this time can simply be. But the body is already preparing to conceive, which should happen in ovulation. And at the third week of pregnancy, the most fertilization occurs from which the process of growth and development of the future person begins.

How to make feelings in the third week of pregnancy?

So, we decided that it was a period of conception of a child. There are practically no special feelings for a woman at this moment. But nature, as always, demonstrates to us wisdom: she can "tell" a woman about the occurrence of ovulation (which means better time for conception). And it is expressed just in the exacerbation of the body's sensitivity, namely:

At the same time, the libido women rises. It becomes more affectionate, active in sexy. Interestingly, externally at this time she reaches the peak of its attractiveness. Nature is intended: all factors for successful conception must come together in the ovulatory period.

Why increases the sensitivity to the smell and taste at pregnancy week?

So far, scientists only suggest that is a prerequisite for such a physiological reaction of the female organism in the ovulatory period. So far, the most realistic looks version that thus the woman is looking for a man's pheromones. In short, she is in the best period for conception - ovulation - physiologically needed sharper react to smells and tastes. Then she "will not miss" ideal for her Pheromones, and the plan for the conception of a healthy offspring will be implemented.

Third week of pregnancy: follow the "tricks" of nature

It's no secret that pregnancy causes forgetfulness. But is it possible to say that during pregnancy, the woman's brain works differently? The body definitely undergo many changes. But how do they affect the brain? Or maybe the change provokes the brain itself?

More than half of pregnant women (perhaps even up to 90%) say that they have been suffering from nausea or vomiting, especially in the morning. After hospitalizing the Duchess of Cambridge Kate Middleton, people started talking about 1% of pregnant women suffer from a heavier and long-lasting morning nausea (Hyperemesis Gravidarum) accompanied by vomiting. Such a state can lead to dehydration and weight loss, as well as demand a medical supervision. Most women's morning nausea passes after 18 weeks of pregnancy.

The causes of the appearance of morning nausea are unknown to the end. Most often it is associated with the body reactions to increase the amount of pregnancy hormone, human chorionic gonadotropin (HCG). Studies have shown a partial connection between HCG and Morning Nausea. In particular, according to observations, the level of hCG in the blood and the frequency of vomiting reaches their peak at the same time. Interesting connection, however, it does not explain why the morning nausea arises.

It is known that the first three months (the first trimester) of pregnancy is very important for the development of the fetus. During this period, a central nervous system is formed, which is a very delicate process, which can easily disrupt the toxins of the mother's blood. According to the new theory, vomiting in the early period of pregnancy performs a beneficial function, eliminating the body from food, which can disrupt this important stage in the development of the fetus.

vomiting is controlled by the area in the back of the marrow, called postmo. It is important to note that posturma does not have a hematorecephalic barrier, therefore, it can detect toxins in the blood and the spinal fluid. Studies also showed that posturma has receptors for HCG, which can explain why it is especially sensitive during pregnancy.

"Theory of toxins" is confirmed by a number of facts: Morning nausea is more common in countries where people use unhealthy food; Nausea is observed only in humans (in the end, we have a very diverse nutrition), and more severe morning nausea is associated with a low level of risk of miscarriage. In addition, many women naturally reduce the amount of meat consumed, fish, certain fruits and vegetables during this period.
