The first signs of pregnancy before the delay

The onset of pregnancy is a very important event in the life of any woman.For some, it is joyful and long-awaited, for others - on the contrary.But, one way or another, everyone wants to learn about the beginning of the development of a new life as early as possible, if possible, already in the first days after conception.

The reason for suspecting the onset of pregnancy for most women of reproductive age with a regular cycle is a delay in menstrual periods.Finally, two strips dissipate the doubts when the test is done independently and the district gynecologist's conclusion.

How many days can you find out about pregnancy?

In order to correctly answer this question, it is necessary to understand the event from which the pregnancy period is measured.

Note: in obstetrical practice, the beginning of pregnancy is counted from the first day of the onset of menstruation.

If to speak about obstetric term, then early signs of I-II weeks of pregnancy simply can not be, becauseIn this period the woman is not even pregnant yet.The actual onset of pregnancy is associated with the day of ovulation - the day when a mature egg leaves the ovary in the fallopian tube and meets there with a viable sperm that can penetrate its membrane and fertilize.

It is difficult to calculate this day, but it is he who is the beginning of the embryonic period of pregnancy.Usually ovulation occurs 14 days before the start of the menstrual cycle, i.e.With a cycle of 28 days a woman can become pregnant sometime on the 14th day after the start of the last menstruation.

Note: must be remembered that the ability of the egg to conceive in the uterus persists for 12-36 hours, and the date of ovulation can be shifted for a variety of reasons, so it is almost impossible to pinpoint the date of conception.

Was there unprotected sexual intercourse on the day of ovulation?Spermatozoa can maintain their viability in the female genital tract for about 1 week, "waiting" for a mature egg.It is for this reason in determining the duration of pregnancy can not be guided by the days of the last sex.

Of course, all of the above does not concern the determination of the period of pregnancy with IVF and planned conceptions under the control of the test for ovulation.In such cases, the date of the beginning of the birth of a new life is always known.

As you understand, all the statements of the woman that she began to feel the first signs of pregnancy in the 1-2 week of the obstetric period can be considered intuitive.

However, there are also quite real physiologically grounded early signs that the ovum is fertilized.They can be felt not earlier than 3 weeks of pregnancy( for obstetric terms).

First signs of pregnancy

The onset of conception is a signal to the body for the beginning of a serious hormonal adjustment and the preparation of organs and systems for subsequent pregnancy.It is these hormonal changes that provoke changes in the state that can be considered the harbingers of a new period in the life of a woman.

Important: The main hormones that cause the first signs of pregnancy are progesterone and chorionic gonadotropin.

The main task of progesterone is to reduce the excitability of the uterus, to prepare the conditions for attaching the fetal egg to its inner layer, to ensure the growth of the mammary glands.An increase in the amount of this hormone is fraught with a change in mood for a woman: she may have irritability, tearfulness, drowsiness.In a number of cases, fluid retention( edema) is provoked, heartburn or nausea may occur.

The journey of a fertilized cell through the fallopian tubes to the uterus takes about a week.In this case, the merged male and female cells turn into a small ball filled with liquid.Having fallen into the arms of the uterine epithelium, he begins to look for a convenient place and is attached to the walls.It is from this moment you can talk about pregnancy.

Embryo attachment itself is often accompanied by discomfort in the lower back or lower abdomen, with slight bleeding.These are the key signs of pregnancy, appearing at 3-4 weeks on obstetric terms( one of the first signs of 1-2 weeks of pregnancy according to the embryonic period).

Successful attachment of the embryo triggers an accelerated process of producing another pregnancy hormone - chorionic gonadotropin ( HG), which is designed to protect the woman's embryo and body from unfavorable factors and future loads.

It stimulates the production of progesterone and estrogens and triggers the processes of renewal of cells of various organs and tissues.And this means that in the body of a woman and further there will be changes that can be regarded as the first signs of pregnancy.Their peak of development occurs after 3-4 weeks of obstetric( 1-2 weeks of embryonic) gestation, but some women begin to notice these changes literally from the first weeks after fertilization.Let's talk about them in more detail.

Drowsiness and nausea

Nausea in the morning is one of the most common early evidence of conception.Unpleasant feelings develop immediately after awakening and are constantly exhausting.It is not excluded also the appearance of vomiting, so the sensitivity of the emetic center increases against the background of increased secretion of hormones.

Important: morning sickness does not always indicate the onset of pregnancy;It is one of the important diagnostic signs of diseases of the digestive tract( in particular - the stomach).

Sensation of drowsiness and general weakness often occur, even against a background of full sleep at night.If there is a regular lack of sleep or a change in work schedule, this aggravates the situation, leading to a sharp decline in mental and physical performance.

The appearance of nausea, drowsiness and a number of other signs is due to certain changes in the neuroendocrine regulation of the body's functions in the development of the fetal egg.

Breast augmentation

Breast augmentation and darkening of the nipples during pregnancy are observed in almost 100% of patients.In some cases, already at the earliest stages, a woman feels uncomfortable with the fact that the brassiere becomes somewhat cramped.

Important: does not exclude a sudden increase in the sensitivity of the breast and even the appearance of soreness when touched.

Change in taste and smell

Suddenly, changes in the sense of smell can be an early sign of pregnancy 1-2 weeks after conception.As a rule, the intolerance of sharp odors develops.Aromas that used to be liked often cause severe nausea.

Already in the first days after conception, a change in taste is possible.Most often there is an irresistible craving for food with a salty or sour taste( for example - to home marinades).

Increased salivation

Increased saliva secretion( hypersalivation) is caused by the irritation of the salivary center in the nuclei of the medulla oblongata against the background of changes in the hormonal background.

Important: If hypersalivation occurs and saliva is regularly swallowed, there is a possibility of a change in the pH of the gastric juice and the development of hyperacid gastritis and other diseases of the digestive tract( esophagitis, ulcer, etc.).

Emergence of vaginal discharge

After 6-12 days from conception, spotting may appear.Their volume is small - within a few drops.The appearance of the discharge is one of the signs of the successful introduction of a fertilized egg into the endometrium of the uterus.This symptom of pregnancy is not typical for all women;It is only one of the variants of the norm.

Basal temperature change

Increased basal( rectal) temperature is due to increased progesterone production and estrogen release.Normally, it grows just before ovulation and decreases after it, if conception does not occur, because the hormonal level comes back to normal.When pregnancy occurs, the amount of progesterone in the blood does not decrease, but, on the contrary, increases, which leads to an increase in temperature indicators.

Important: with constant measurement of basal temperature the woman marks so-called."Implantation sinking", in which, for one day of the second phase of the cycle, the temperature drops sharply under the influence of estrogen release, and then it also sharply increases( already under the action of progesterone).

In this case, the thermometer will be 37 ° C or slightly more.Such figures are one of the main first signs of pregnancy, observed in the first weeks after fertilization, when the placenta has not yet started functioning.

Bacterial, viral and fungal infections

After conception, the activity of the immune system decreases.This is necessary to ensure that the female body does not perceive the embryo as an alien object, because it contains only half of the "native" genetic material.As a consequence, the body becomes more vulnerable, and general ailments( including colds) begin to bother more often.

Note: is one of the first signs of pregnancy 1-2 weeks after fertilization( 3-4 weeks of obstetric term) include headaches for no apparent reason and an increase in body temperature, also not associated with obscheomatic diseases.These symptoms are explained by changes at the hormonal level.

At the local level, the reproductive system from infectious agents is protected by increasing the concentration of hydrogen ions in the secretion of the vagina.But this environment favors the growth and reproduction of yeast-like fungi of the genus Candida.As a result, often at the earliest possible time, vaginal candidiasis, more commonly known as thrush, develops.

Important: if there is at least a minimum likelihood of conception, you can not treat a malaise with pharmacological agents without first consulting a physician, since even conventional analgesics and antipyretic drugs can seriously harm a future child.

Feeling of heaviness in the lower abdomen is another first sign of pregnancy

With the onset of pregnancy, blood flow to organs located in the pelvic area is significantly increased.Some women begin to feel their uterus already in the first days after conception.

The rush of blood affects the functioning of the urinary organs.Increases the filtration activity of the kidneys, and the bladder is filled faster, and in this connection, early in pregnant women urge to urinate.Many even have to get up 2-3 times at night.Gradual normalization of functions is noted only in the second trimester.

Pain in the lumbar region

Pregnancy may be indirectly indicated by severe intense pain in the lumbar and sacral region( so-called "lumbago").This first sign is associated with the periodic reduction of the uterus at an early pregnancy.But it should be borne in mind that such pains are much more often diagnostic signs of problems on the part of the musculoskeletal system( spine diseases).

Edemas

Already at the earliest time, in some cases, moderate swelling of the legs is noted.It is caused by the delay of water and salts against the background of increased secretion of progesterone.

Change in blood pressure indicators

Active hormonal alteration shows itself a significant decrease in blood pressure.Since progesterone has an antispasmodic effect on the smooth muscle elements of the vessel walls, the indices of systolic and diastolic pressure in early pregnancy may drop below 90 mm.Gt;Art.Because of arterial hypotension, there are signs of deterioration in overall well-being, dizziness and, in some cases, fainting.

Nervous System Disorders

Often already at the earliest time, a woman's concentration ability is noticeably reduced, and her behavior appears to be somewhat uncorrupted.For many, forgetfulness is also characteristic.

In a number of cases apathy develops, that is, complete detachment, indifference and indifference.Changes in the mental state are caused by increased secretion of progesterone.As the gestation period increases, its effect is compensated by an increase in estrogen production.

Decreased libido

Sexual desire is reduced, starting from the first days after conception, but it is normalized to the second trimester.This fact can also be regarded as the first sign of pregnancy.

Important: already from the first week in some women there are signs of mild toxicity.

Folk methods of pregnancy detection in the first days after conception

"Grandmother's methods" for determining pregnancy before delaying scientific justification do not have.It was once thought that the appearance of vascular sprouts on the chest in the "decollete zone", snoring in the dream and a metallic taste in the mouth are said to have occurred about conception.Despite the absence of specific explanations, such early signs of pregnancy are noted by many women, so ignoring them is not worth it.

Why is the early diagnosis of pregnancy important?

Early manifestations are a good reason to conduct tests and identify a pregnancy.In this case, the important point remains to determine the location of implantation of a fertilized egg.

The placement of the fetal egg in the uterus is normal.If an ectopic pregnancy is diagnosed, the patient needs urgent medical attention to prevent serious complications.

The sooner a woman learns that she will be a mother, the more chances that pregnancy and childbirth will flow without complications.The appearance of one or several early signs is an unconditional basis for the immediate abandonment of bad habits, making adjustments to the diet, stopping medications with embryotoxic and teratogenic effects, and normalizing sleep and rest.
