Pregnancy can occur if the ovum that comes out of the female’s ovary fuses with one of the man’s sperm, resulting in a fertilized ovum, and this fertilized ovum begins its journey towards the uterus, as it adheres to the uterine wall through a process known as the process of implantation, and these complete stages need about two weeks Up to three weeks after sexual intercourse, until pregnancy is announced.
As for the details of the fertilization process, it often takes place in the fallopian tube, where the ovum remains in the fallopian tube for 12-24 hours waiting to be fertilized, and in the meantime it moves slowly inside the tube, and sperm cells are known to be able to swim through the cervix And the uterus down to the fallopian tubes, and a sperm can survive in the female’s body for up to six days looking for an ovum to fertilize before it dies.
The first symptoms of pregnancy
There are some symptoms and signs that will appear on a woman at the beginning of pregnancy, which can be used to infer the possibility of pregnancy.
However, the female can make a mistake in distinguishing between some of the symptoms and signs of early pregnancy and the symptoms that precede the onset of the menstrual cycle;
This is because the symptoms are very similar, and therefore it is not possible to be certain that there is a pregnancy just because some of its symptoms appear on the woman, but these symptoms are considered general indicators and nothing more, and therefore the woman must resort in the end to take a pregnancy test to confirm the presence or denial of pregnancy. In general, the most prominent primary symptoms of pregnancy can be stated as follows:
One of the first symptoms that a pregnant woman notices is that her period is late than the usual time, however, pregnancy is not the only reason for the delay of the period, in fact there are several reasons that can lead to the delay or interruption of the menstrual cycle,
such as; Weight loss, hormonal imbalance, stress and psychological tension.
In addition, a woman cannot rely on the delay of her period as a pregnancy symptom if her menstrual cycle is irregular.
Hormonal levels vary greatly over the course of pregnancy, and this can lead to many changes in the pregnant woman’s body, including: Some changes to the breast, and for some women this is one of the early signs of the onset of pregnancy.
Some changes may be observed by the pregnant woman on the breasts, such as: breast swelling, increased sensitivity, and pain in the breasts, as well as a change in the color of the area around the nipple.
It should be noted that breast pain can be bothersome in the early stages of pregnancy,
but once the hormones begin to stabilize, most of these symptoms usually disappear.
Excessive urination is a common symptom among pregnant women.
Since the early stages of pregnancy, a woman can feel an increased need to urinate,
and the reason for this is due to the hormonal changes that accompany pregnancy,
and this phenomenon can be observed strongly in pregnant women after the beginning of the sixth week of pregnancy.
During pregnancy, an increase in the proportion of progesterone in a woman’s body is very normal, but this increase can lead to suffering from constipation;
It is one of the unwanted pregnancy symptoms,
which results from the effect of the hormone progesterone in the digestive system, causing it to slow down the movement of food in the intestines.
Constipation can be treated and reduced by staying hydrated by drinking enough water, getting some exercise, and trying to eat a high-fiber diet.
Colic and cramping
When the fertilized ovum begins to attach to the wall of the uterus, some common symptoms begin to appear on the pregnant woman, for example;
The feeling of abdominal cramps is similar to the cramps experienced by the female during the menstrual cycle, so they can be confused due to the similarity of the symptoms accompanying each of them.
These cramps usually start mildly at the beginning of pregnancy,
and then disappear with time,
but if the pain is severe, or if it is accompanied by heavy bleeding, or other worrisome symptoms, it is recommended to see a doctor.
Nausea is one of the most common symptoms among pregnant women,
and although nausea associated with pregnancy is known as morning sickness,
its occurrence is not limited to the morning period of the day,
as a pregnant woman can feel nausea at any time of the day,
but it is more common in the morning.
Fatigue and tiredness
The pregnant woman may feel tired and exhausted from the first weeks of pregnancy. The reason is due to the high proportion of the hormone progesterone at the beginning of pregnancy,
in addition to other factors such as: changes in blood pressure and sugar level. A healthy and balanced diet.
Just like many other early symptoms of pregnancy, cravings for food appear due to changes in the level of hormones after pregnancy, and women can find themselves preferring a certain type of food,
and disliking others, to the extent that these foods or their smell can cause nausea.
Very annoying These cravings for some types of food or aversion to some of them can continue throughout pregnancy,
but in most cases these symptoms disappear at the end of the first trimester.
it is necessary to make sure to eat integrated meals to ensure the health of the mother and her fetus.
The first signs of pregnancy can appear in the form of spotting or light bleeding, sometimes known as implantation bleeding. A woman may notice bleeding when the fertilized ovum begins to attach to the uterine wall,
and this occurs about 10-14 days after the onset of pregnancy.
In addition, in some cases, bleeding may be accompanied by vaginal secretions of a whitish color,
and these secretions appear due to the thickening of the walls of the vagina.
Pregnant women often feel emotional imbalance in the first period of pregnancy,
and again the reason for this is due to the change in hormones caused by pregnancy. Mood swings usually appear during the first trimester of pregnancy, and after a short period things return to normal again.
Physical changes during pregnancy
A woman may notice some changes in her body since the beginning of pregnancy, such as:
- Changing the nature of the skin: the pregnant woman may notice that her skin appears more fresh and shiny.
- Protrusion of the veins under the skin: due to the increase in the amount of blood in the pregnant woman’s body,
and the increase in the work of the heart to meet the needs of pregnancy. Blue veins in the abdomen, breasts, and legs can protrude and become more noticeable.
- Changes in the vagina: The lining of the vagina will become thicker and less sensitive.
