Guide: Why calculate the time for pregnant women to get pregnant?From the moment they knew pregnancy, expectant mothers have been looking forward to the newborn baby.Calculating pregnancy time can make pregnant mothers better protect the fetus, coexist with the fetus, but also make pregnant women feel more secure.How to calculate the pregnancy time of pregnant women?In fact, there is a scientific algorithm.

The obstetrician and gynecologist said: In medical, the normal pregnancy time limit is about 40 weeks. The start time of the first day of the last menstrual period is often used as the start time of the due date. The normal pregnancy time limit is about 265 days.Calculated in one day, ovulation is in the middle of menstruation, so 40 weeks of pregnancy is 2 weeks more than the actual egg fertilization.

However, the menstrual cycle of each woman is different, so when calculating, you must figure out your own menstrual days.For example, a woman takes 28 days as a menstrual cycle, so the 280 -day pregnancy is equivalent to the time of ten pregnancy or ten -month cycle.The statement of conceiving in October also came out.

Calculating the time of pregnancy is convenient for the due date, but it is reminded that the due date is only an estimated value. The actual delivery time is often 1-2 weeks in and out of the due date.Therefore, while referring to the due date, pregnant women should also carefully feel their condition, and use the doctor to check the placenta with the doctor.

If there is still some vague time for pregnancy, we can use formulas to calculate.For example, a woman’s menstruation takes 28 days as a cycle:

When the due date is calculated, the entire pregnancy period is calculated at 280 days. The specific method is:

The expected period month = the month of the first day of the second menstruation +9 or -3,

Number of days in the due date = the number of days on the first day of the last menstruation +7.

The time calculated in this way is due to the due date.For example, the last menstrual period was on February 1, and the month of the month was 2:19 = November, and the date was 117 = 8. Then the due date should be November 8.

If the last menstruation is after April, the method of minusing is taken by 3.If the last menstrual period is April 2, it is April-3 = January of the following year, 2:17 = 9, that is, the due date on January 9 of the following year.

The above is calculated according to the solar calendar. If the due date is calculated in the lunar calendar, the monthly calculation is the same, but the date plus 7 days will be changed to 15 days.

If you still feel that the fog will not count, there are two small methods,

1. One is to search directly on the Internet: The pregnancy cycle calculator will have a special applet to help you calculate; the other is that the mother and baby company or hospital will have a pregnancy cycle calculation comparison table.Essence

The first 5 days of the ovulation period is 10 days. During this period, the duration rate of the same room is high. If you want to know the ovulation day, you can go to the hospital for B -ultrasound testing.

Pregnancy is a big deal, please be cautious.There are a few points to pay attention to calculating the pregnancy time of pregnant women:

1. When calculating, the default normal pregnancy time limit is about 40 weeks. It often takes the first day of the last menstrual period as the starting time of the expected due period. The normal pregnancy time limit is about 265 days;

2. We often say that in October, we will be calculated based on a woman for 28 days as a menstrual cycle, because its 280 -day pregnancy is equivalent to ten pregnancy or ten -month period cycles.

3. Calculating formula: The month of due date = the month of the first day of the last menstruation +9 or -3, the number of days of the due date = the number of days on the first day of the last menstruation +7.
