The earliest signs of pregnancy manifested in different ways: someone they are visible at once, but there are women who do not see their first pregnancy before fetal movements. In most cases, the first signs are not too intense, and you can see them, but carefully watching their condition.
What happens in a woman's body after conception
After conception, a woman's body there are numerous very serious changes, first at the level of the central nervous system (CNS), and then on the humoral level and in the internal organs.
Once in the central nervous system is signaled that fertilization took place, it greatly reduces the excitation processes, mainly dominated braking processes. The cerebral cortex forms the dominant center of pregnancy, which allows the central nervous system to constantly monitor the state and development of the fetus and the pregnancy as a whole. At the same time signals of the pregnancy comes from the cerebral cortex to the subcortical region in the hypothalamus, which is responsible for the condition of the entire endocrine system. The hypothalamus in turn instructs the pituitary gland (the main endocrine glands, which is also located in the brain), and the signals from the pituitary gland and the ovaries go to other endocrine glands (thyroid, adrenal).
Profound changes are taking place in the endocrine system. The main hormone of the first month of pregnancy is progesterone
Progesterone - norm and pathology
That is allocated by the corpus luteum of the ovary (a temporary endocrine gland formed on the spot ruptured follicle from which came out mature egg). To stimulate its production starting another pregnancy hormone - human chorionic gonadotropin (hCG), which begins to produce shell embedded in the uterine wall of the embryo in the second week of pregnancy. During the first months of pregnancy the amount of HCG is constantly growing, resulting in a yellow body grows and begins to intensively produce the female sex hormones estrogen and progesterone.
During pregnancy, the influence on the body of the vagus nerve (long nerve that runs from the brain and supplies the organs of the neck, chest and abdomen). This is especially noticeable at the very beginning of pregnancy, when the woman suddenly changed the taste, she begins to perceive differently the different smells, feels frequent dizziness
Dizziness - if the ground is slipping from under his feet
, Nausea, sometimes - vomiting and profuse salivation.
As a result of the coordinated work of the entire endocrine system fully hormonal changes a woman, and under the influence of hormone changes, all its internal organs and systems. All this is shown next to the earliest signs of pregnancy.
The earliest signs of pregnancy, what are they?
Since during pregnancy in the central nervous system inhibitory processes dominate the very first sign of pregnancy
The first signs of pregnancy to delay: Eyes on intuition?
to lethargy, drowsiness and decreased disability. Drowsiness may be so severe and unexpected at the same time (especially if the woman before pregnancy was mobile and energetic) that it is not able to cope with this condition and sometimes falls asleep on the job.
Another early sign - bouts of nausea in the form of dizziness, which most often appear in a stuffy room. Most often attacks of dizziness are associated with a decrease in blood pressure
Blood pressure - dangerous if his swing?
, Which in turn depends on the extension and spasm of blood vessel walls. It controls the reduction of blood vessel walls autonomic nervous system, which has not yet adapted to the new state, so that blood pressure may increase, then decrease. Bouts of nausea can be accompanied by nausea.
Hormonal shifts act on the sense organs, which react in the early stages of pregnancy. The changes affect mainly organs of taste and smell. Changes in taste can be very peculiar. In the first place there is usually a metallic taste in the mouth, making changes and taste of all dishes. It was a metallic taste often causes a woman to give up favorite foods. Different women have their eating habits: someone wants something sharp little or smoked, and someone - sweet. This taste can vary significantly.
Changes of smell also occur every woman differently. Some women literally chase odors. Because of this, they can not travel on public transport (smells strange perfume, sweat, tobacco smoke), go to the grocery store (there also can meet different smells unpleasant for pregnant women) and even be in your own kitchen (where odors can be totally intolerable).
Finally, under the influence of estrogens in women is increased and breast tenderness.
