Pregnancy weeks and the date of birth are important matters for every woman who is waiting for the happiest moments of her life to become a mother. When you show signs of pregnancy Caldoar and vomiting and stop the menstrual cycle women often go for a test of pregnancy and when the fetus begins the period of pregnancy and pregnancy begins pregnancy account in weeks, months , and hours they are waiting for her son.
The stopping of your period is one of the first clear signs of pregnancy, and after confirming the pregnancy, you must wonder how many weeks of pregnancy and how the weeks of pregnancy can be calculated correctly, and what is the importance of the pregnancy calculator to determine the exact date of birth.
- Pregnancy occurs when a female egg meets a male sperm to become a fertilized egg.
- This fertilized egg implants in the wall of the cervix to begin forming the fetus, which will turn after nine months into a small baby.
- The placenta forms the only link between the fetus and the outside world, and from it obtains the materials that help it grow and form the elements of its body.
- That is why a woman must take care of her nutrition and the nutrition of her fetus, and she should stop taking birth control pills if she is sure of her pregnancy.
- The woman and her fetus undergo various physiological changes, starting from the first week of pregnancy until the time of the birth of the newborn.
Calculating the weeks of pregnancy:
- Pregnancy weeks can be calculated in a simple way by considering every 4 weeks as one month of pregnancy.
- Doctors use this method in order to determine the estimated due date as they leave a week or two after the date of the first day of the last menstrual period.
- You should also know that the date of delivery takes place before the end of the 40th week of pregnancy.
- This method is used in order to calculate the date of birth and is correct in most natural cases once the first day of the last menstrual period is known.
Number of weeks of pregnancy:
According to many modern scientific studies, and as reported by the American Obstetrics and Gynecology website , the weeks of pregnancy are divided into 3 stages:
- The first stage of pregnancy extends from the first week of pregnancy (1) to the twelfth week of pregnancy (12).
- The second stage of pregnancy extends from the thirteenth week (13) to the twenty-eighth week of pregnancy (28).
- The third stage, which ends with childbirth, extends from the twenty-ninth week (29) to the fortieth week (40).
There are weeks of pregnancy, a woman goes through with her side with different symptoms and signs that vary from week to week from the beginning of pregnancy in the first week until the last week of pregnancy. Let us know the weeks of pregnancy in detail:
The first week of pregnancy:
- It is the first stage of the beginning of pregnancy and changes begin in the uterus to receive the fertilized egg and incubate the fetus.

The second week of pregnancy:
- The second week of pregnancy is similar to the first week in that the symptoms are not visible in general.
- And you may see some spots of blood in it, which indicates the implantation of the fertilized egg in the lining of the uterus.
Third week of pregnancy:
- In the third week of pregnancy, the fertilization of the fertilized egg with the male sperm is completed to form the fertilized cell, which is known as the zygote.
- In the zygote cell, the chromosomes that carry the hereditary traits of the pair combine to determine traits such as (hair color, eyes, etc.).
- The zygote divides into a number of cells rapidly throughout its transit through the fallopian tubes to the uterus until all the organs of the fetus have formed.
Fourth week of pregnancy:
- After four weeks of pregnancy, the embryo attaches to the uterine wall and the actual stage of division of the cells that make up the organs of the fetus begins.
- At this stage, the amniotic sac or amniotic sac is formed that surrounds the fetus and provides protection for it.
- It also sticks to the amniotic sac, the yolk sac, which provides nourishment to the fetus in the first weeks of pregnancy.
- At this stage, the fetus is very small, the size of a grain of rice, so it cannot be seen in the imaging equipment at this stage.
