Women and pregnancy
From the first day the woman knows that she is pregnant and feels nostalgic, she tries eagerly to know the date of her birth, to count the days and hours, calculate the age of her fetus at each stage of her pregnancy, and eagerly awaits the day that she sees her child, and when her first visit to the doctor, Either manually or through a ultrasound scan that accurately calculates the age of the fetus.
Age of the fetus
Pregnancy begins on the first day of fertilization, but there is no way to determine that exact day, since fertilization occurs after the end of the menstrual cycle, and is likely to occur in the days of ovulation, ie from the tenth day to the fourteenth day, but in calculating the age of the fetus and the date of birth We calculate the first days of pregnancy from the second day of the end of the last menstrual cycle, where the age of the fetus is calculated by the weeks, and the date of birth is calculated after the expiry of 40 weeks from the beginning of the first day of pregnancy by about 9 months.
Method of calculating fetal age
The four weeks should not be considered as a month, because 4 weeks (28 days) is not equal to 30 (30 or 31 days). There is a difference in the date of birth of the pregnant woman.
- If the day following the end of the last cycle is 10/10/2015 for example, it rest on the end of the month 21 days ie 3 weeks.
- We come for the next month We count for 4 weeks and add it on the first 3 weeks to become 7 weeks, keep several days less than a week we write aside,
- We come for the following month and count four weeks and add them to the above, and add the remaining days of the month to the days we left aside, so we count the rest of the months.
- Finally, we collect the days we left aside and count them weeks. We combine them for the past 40 weeks, and we consider the last date we stopped at the last date of birth, and in the same way we calculate the age of the fetus at any stage in pregnancy.
Three stages of pregnancy
Doctors divide pregnancy into three stages:
- The first stage starts from the first week until the thirteenth week, the fetus begins in this period to grow and develop, and its main organs begin to form, such as the brain, heart, lungs and stomach, and at this stage the symptoms of pregnancy in women begin to appear as nausea, exhaustion and fatigue.
- The second stage starts from the 14th week until the twenty-sixth week, when the fetus begins to move, its muscles and bones grow, the fetus weighs about one kilogram, and the symptoms of pregnancy decrease in women at this stage.
- The third stage is complete where the organs of the fetus and manages the body to prepare for the stage of birth, accompanied by pain in women in the lower abdomen and back because of the weight of the fetus.
