Determination of the date of labor for the last menstruation.The date of labor for the last menstruation is calculated by the formula: 1 day of the last menstruation (exact date) - 3 calendar months + 7 days = date of the expected delivery. For example, the last menstruation began in a woman on November 19, 2013. Hence, November 19 - 3 calendar months + 7 days = August 26, 2014. It is worth noting that determining the date of delivery for the last menstruation is the most reliable way to find out the approximate date of birth of the baby. Of course, he is relevant only if the woman remembers the day of the beginning of the last menstruation.

Determination of the date of delivery for ovulation. This method can be used only for women with a regular menstrual cycle. The beginning of the menstrual cycle is the first day of menstruation. The cycle lasts until the next menstruation begins. Duration of the cycle in different women can vary. Most often the duration of the cycle is 28-30 days. Ovulation - the release of the egg from the ovary and this process occurs in the middle of the cycle. If the duration of the menstrual cycle is 28 days, then the day of ovulation is the 14th day of the cycle, and if the cycle lasts 30 days, then ovulation occurs on day 15. To calculate the date of birth for ovulation, you need to use the formula: the expected day of menstruation - 14 days + 39 weeks = date of birth. For example, the date of the last menstruation: November 19, 2013, the duration of the cycle for a woman 28 days. Hence, the expected day of menstruation - December 16, 2013. Now you can apply the formula: December 16, 2013 - 14 days + 39 weeks = September 1, 2014.

At the first appearance. Calculate the period of delivery for the first turnout is possible only if the woman was registered before the 12th week of pregnancy. Given the findings of the examination, the size of the uterus, the doctor can make a conclusion about the period of pregnancy. And then by this time it is necessary to add the remaining weeks. For example, a woman registered on 04.01.14 years and the doctor determined that the gestational age is 6 weeks. Hence, by the date 04.01.14, the remaining 34 weeks of pregnancy should be added. The term of expected delivery is August 29, 2014.

According to the conclusion of ultrasound. Ultrasound examination, depending on the size of the fetus, can clarify the duration of pregnancy. Suppose a woman made ultrasound on 11.03.14 years and according to the conclusion of ultrasound, the gestation period is 17-17.5 weeks. So it is necessary to add the remaining 23 weeks to 11.03.14. Term of delivery is August 28, 2014.

According to the woman. Sometimes a woman can accurately indicate the date of conception, so a pregnant woman is necessarily interested in when she thinks she will give birth. Thus, the woman from our example should give birth between August 26 and September 1, 2014.

Tip 2: How to determine the date of birth by first stirring

For some women, the birth of a child is,almost the most important event in life. In order to prepare for this accomplishment, it is necessary to know the expected date of birth, which can be determined by several methods, including the first movement of the fetus.

Instructions

1

Typically, the movement of the fetus in womenis observed during the period from 18 to 21 weeks of pregnancy. Rarely, but it happens when it happens on 14, and even at 25 weeks. In fact, the period of the first stirring of the baby in the womb depends on the individual characteristics of the woman's body.

2

Women of a more dense complexion are much more difficultTo recognize the first perturbations, than to those who have a slender figure. In addition, those who have the first pregnancy do not know what are the sensations when the baby is moved in the uterus, so they may not notice this fact at once. But women who have already given birth, are quite capable of feeling earlier shifts. The period of the first movement of the fetus depends on the thickness and sensitivity of the walls of the uterus.

3

In any case, knowing the day of the first stirringfetus, you can determine the approximate date of the forthcoming birth. For this, to the number when the first intrauterine movement occurred, add 20 weeks, which is half the time of the entire pregnancy. It's only if you are a primiparous woman, if it's a recurrent woman, add 22 weeks. The received date will be the probable date of delivery.

Please note that one should not believe completelythe results of this calculation because of the subjectivity of perception of the first intrauterine movement of the fetus. Some women may make mistakes and take the usual intestinal peristalsis for the first manifestation of the baby's movement.

A more accurate birth date can only be seta skilled gynecologist who observes pregnancy. He defines it, based not only on the date of the first perturbation, but also on the date of the last menstruation, the date of conception, the size of the uterus, the results of the blood test for hCG, and the results of ultrasound (ultrasound). As a rule, the last indicator gives more accurate data.
