How to use the ovulation period to calculate the expected date of birth? After knowing that the ovulation period can be quickly pregnant, so use this great opportunity to get pregnant, surprise, full of expectation that the baby will come early, the problem can come again, how should the ovulation period be calculated? When is the baby born? This has become one of the many problems that mothers want to know. Let’s take a look at this issue in detail. How to use the ovulation period to calculate the expected date of birth? The entire pregnancy is about 40 weeks, that is, 9 months and 7 days, 287 days. The expected date of birth can be estimated by the last menstrual period. The calculation method is based on the first day of the last menstrual period, the month is reduced by 3 or increased by 9, and the number of days is increased by 7. However, the actual delivery date and the estimated expected date of birth may differ by one to two weeks. If the last menstrual date of the pregnant woman is unclear or the menstruation is not accurate, the doctor is required to calculate the expected date of delivery. Only 5％ people were born on the day of the due date. Usually after you know that you are pregnant, the doctor will help you calculate the date of delivery. There are two methods for calculating the production date in general, one based on the sexual life date or ovulation period that causes the pregnancy, and the other based on the date of the last menstrual period. Since most people have difficulty remembering that it is difficult to determine the date that caused the pregnancy, the clinically common calculation method is based on the first day of the last menstrual period. This means that you may realize that you are pregnant when your next menstrual period is late, and you are actually pregnant for at least 2 weeks. The period of childbirth calculated according to the date of the last menstrual period is actually the week of the last menstrual period as the first week of pregnancy. The gestation period is usually about 280 days, which is 9 months and 1 week. There is a formula for calculating the baby’s date of birth: month +9 (or -3), date +7. The menstrual period is 3-5 days, even if you are 3 days, the last menstrual date is November 28, 2004. Example: The last menstrual date is November 28, 2004. The expected date of delivery is: November – March = August, 28 + 7 = 35, the following year’s September; 35-31 = 4 days. The expected date of delivery is September 4, 2005. If the menstruation is not accurate, it can be calculated based on the time when the fetal movement begins to appear. The first fetal movement has a first fetal movement of approximately 1820 weeks, and the expected date of delivery may be after 2022 weeks. It is also possible to measure the fetus or the amount of the fundus height according to the ultrasound. Using these methods to analyze the combination at the end of pregnancy, you know when your baby will be born. If this pregnancy is successful, then the next expected date of birth will be 266 days plus your ovulation date. This is because the usual due date is calculated from the first day of the last menstrual period, plus 280 days (40 weeks). In fact, the correct algorithm should be when the sperm and egg are combined and start to be implanted, plus 266 days. If you can remember the ovulation day accurately and have the same room, the expected date of birth calculated in this way is very accurate.
