When pregnancy began

Pregnancy

Pregnancy begins with the fertilization of a female egg by a sperm inside the fallopian tube (English: Fallopian tube), to produce what is called a fertilized egg (in English: Zygote), which passes through a number of divisions to become a mass of cells called an embryo (in English: Embryo). The wall of the uterus (in English: Uterus) and the growth processes of the various organs begin and the formation of nerves, bones and blood, to be called after that a fetus (in English: Fetus); Where it is surrounded by amniotic fluid. The fetus depends on the placenta (English: Placenta) to obtain food, oxygen, and waste disposal, and the pregnancy usually lasts for forty weeks, which is approximately nine months, and during which the pregnancy is divided into three or three stages (English: Trimesters), and it is worth noting thatA absence of a natural period is the main indication of pregnancy . [1] 

Initial pregnancy symptoms

There is a group of symptoms that give an indication of the possibility of a pregnancy in a woman, and some of these symptoms appear near the time of a missed period or after a week or two after that; Sixty percent of women feel symptoms of early pregnancy in the sixth week of pregnancy , while ninety percent of them feel symptoms in the eighth week of pregnancy, and women differ in pregnancy symptoms and the symptoms differ from pregnancy to another with the same woman. [2] [3]

It is worth noting that symptoms alone are not sufficient to confirm pregnancy . As the symptoms of primary pregnancy are similar to the symptoms of normal premenstruation resulting from fluctuating and changing levels of the hormone estrogen (English: estrogen) and progesterone (in English: progesterone) in the blood, and symptoms may appear as a result of a false pregnancy (in English: pseudocyesis) A woman suffers from real pregnancy symptoms such as an enlarged abdomen and changes in the breast, but without an actual pregnancy. Based on the above, the only way to confirm the existence of a pregnancy is to perform a pregnancy test. [2] [4]

When the initial symptoms of pregnancy appeared

A woman may not feel pregnancy symptoms during the first few weeks of pregnancy, because the pregnancy period is calculated from the date of the last menstrual period; The last period before pregnancy is the first week of pregnancy, even though the woman is not yet pregnant. The following is the timeline for a set of early pregnancy symptoms: [5]

Display When the symptom occurred 

Mild cramping and spotting The first to the fourth week

Missed period fourth week

Tired The fourth or fifth week

Nausea Fourth to sixth week

Pain or tingling in the breasts Fourth to sixth week

Frequent urination Fourth to sixth week

Bloating Fourth to sixth week

Motion sickness The fifth to sixth week

Mood Swings the sixth week

Changes in temperature the sixth week

Hypertension The eighth week

Extreme fatigue and heartburn The ninth week

Increased heartbeat The eighth to the tenth week

Changes in the breast and nipples The eleventh week

Acne appears The eleventh week

Significant weight gain The eleventh week

Facts about initial pregnancy symptoms

The following are the most common early pregnancy symptoms : [2] [5]

Colic and spotting: The cause of spotting or light vaginal bleeding is the implantation of a fertilized egg in the wall of the uterus to cause what is called implantation bleeding (in English: implantation bleeding), and colic is (in English: light and cramping) For menstrual cramps and pain, a woman may also notice the presence of milky white vaginal secretions, the main cause of which is an increase in the thickness of the vaginal wall.

Changes in the breasts : The rapid change in hormone levels during pregnancy may lead to some changes in the breast (in English: Breast Changes), such as swelling, or pain when touched, or fullness and heaviness, or tingling, and the color of the nipple may become (in English) : Areola) is darker. It is worth noting that the woman's body gets used to the new level of hormones, and the feeling of these changes is reduced.

Absence of a menstrual period: Missed period is due to the body's production of the hormone chorionic gonadotropin (in English: Human Chorionic Gonadotropin), which is the hormone responsible for maintaining pregnancy and alerting the ovaries to stop the process of ovulation (in English: Ovulation) every month .

Fatigue: The high progesterone hormone is the main cause of feeling tired (in English: Fatigue), and sometimes drowsiness, and other factors such as low blood sugar, low blood pressure, and others may help it.

Morning sickness: Nausea (English: Nausea) or vomiting (English: Vomiting) can occur at any time during the day, but it often occurs in the morning, and although the cause of morning sickness is unknown (English: Morning Sickness), Hormones change during pregnancy may play an important role in its occurrence.

Desire or aversion to food: Some pregnant women suffer from a strong desire (in English: cravings) towards certain types of food, or they may suffer from aversion (in English: Aversions) to some types of food, and the reason for that is hormonal changes during pregnancy, Smell sensitivity that occurs in some women during the first trimester of pregnancy (First trimester) may also contribute to provoking nausea and aversion to food.

Mood swings: The high level of hormones during pregnancy makes the woman more emotional and moody. Where her feelings vary between depression (in English: Depression), irritability, severe mood (English: Irritability), anxiety (English: Anxiety), and euphoria (English: Euphoria).

Frequent urination: frequency of urination ( in English: Frequent urination) occurs when women are pregnant as a result of increased blood pumped by the heart amount, thereby increasing the amount of urine out of the kidneys and bladder accumulated, as hormones play a pregnancy an important role in this too.

Constipation: the rise in the hormone progesterone slows down the movement of the digestive system and thus causes constipation (English: Constipation), which in turn may cause bloating in the abdomen.

Other symptoms of pregnancy : such as a high basal body temperature (English: Basal Body Temperature), increased heart rate (English: heart rate) due to pregnancy hormones, feeling dizzy due to low blood pressure and expansion of blood vessels, and a feeling of heartburn (English: Heartburn) As a result of the relaxation of the valve connecting the stomach and esophagus.

Pregnancy checks

After the appearance of one or more of the common pregnancy symptoms it is recommended to do a pregnancy test to confirm the presence of pregnancy. [6] The pregnancy test is based on examining the content of the human chorionic gonadotropin hormone in the urine or blood, which the body usually manufactures six days after fertilization occurs. (English: Fertilization); That is, after the fertilized egg implantation in the lining of the uterus, it is worth noting that this hormone continues to increase significantly throughout pregnancy. [7] The following is a simplified explanation of the two main types of pregnancy exams:

Urine test

Often women do a urine test one week after the absence of their period, and a urine test can be done at home or in the doctor's office. It features a screening home pregnancy ( in English: Home pregnancy test) that is easy to use, and inexpensive, and quick to show results within minutes on the line shape or color or symbol, and is very accurate if it is used strictly according to the instructions. [7]

blood test

Using a blood test can detect the pregnancy hormone after his presence in the body very short period, unlike urine test that needs longer than the presence of the pregnancy hormone in the body to give a positive result, but more expensive, and needs a longer time to see results, there are two types of blood test: [ 6]

Qualitative hCG blood test; The qualitative examination reveals the presence of this hormone in the blood or not, thus confirming the presence of pregnancy or not.

Quantitative hCG blood test. It measures the specific amount of the hormone in the blood, even if it is a relatively small amount, so it is considered a very accurate examination.
