How many months of pregnancy can be born, how many months of pregnancy can be born?

It usually takes a few months before a baby is born.

The normal time limit of pregnancy is about 40 weeks, and the first day of the last menstrual period is often used to calculate the start time of the expected date of delivery, and the normal pregnancy time limit is about 265 days (referring to the day when the egg is fertilized), and ovulation is in the middle of menstruation, so 40 weeks (280 days) of pregnancy is 2 weeks longer than the pregnancy time calculated from the beginning of the actual egg fertilization. If a woman's menstruation is 28 days as a menstrual cycle, then 280 days of pregnancy is equivalent to ten gestational months (28 days is a menstrual cycle) or ten menstrual cycles, so there is a saying that the pregnancy is in October.

It is possible to have a baby in the first few months of pregnancy.

The first day of pregnancy is actually the first day of your last menstrual period! So 280 days, including the day of your last menstrual period! In fact, it should be about 265 days after conception!

That's just the due date, in fact, most people don't get to or beyond that date! Babies born between 37 and 42 weeks of pregnancy are normal.

Generally speaking, 356 days of pregnancy (the number of days of pregnancy is calculated according to the first day of the last menstrual period) will have pregnancy reactions, such as nausea, vomiting, etc. are signs of early pregnancy, if these symptoms are found, you should go to the hospital to diagnose, if it is determined that you are pregnant, you should do a good job of protecting the fetus in time.

Pregnancy usually takes place at about 10 months of pregnancy, but some women are pregnant until about 37 or 38 weeks of term. Some pregnant women may give birth before a month, that is, less than 37 weeks, which is called a premature baby. Premature babies are not in the best physical condition as full-term babies, so it is important to protect yourself during pregnancy and avoid premature birth.

As the saying goes, conceived in October and conceived in October, the normal situation is naturally to be 10 months pregnant before it can be delivered. However, it varies from person to person, there are 7 months, 8 months, and 9 months, and 7 months and 8 months are called preterm birth. Nine months and ten months are normal production.

Generally, premature babies are less than a month old and very small, and their eyes are generally not open when they are born.

Many women who have just become pregnant do not particularly understand the time and cycle of pregnancy, and the lack of pregnancy knowledge is very dangerous for pregnant women, so it is necessary to understand the basic pregnancy knowledge in advance, so as not to have a series of symptoms and cannot make a judgment when the time comes.

Under normal circumstances, you can give birth after 10 months of pregnancy, and medically stipulates that the total number of days of pregnancy for women is 280 days, and each gestation month is 28 days, for a total of 10 months, so pregnant women will give birth when they are 10 months pregnant.

Many pregnant women are more worried that they can not correctly calculate the time of pregnancy and delay the time of delivery, in fact, this situation is not too worried, if it can not be detected, you can go to the hospital for a blood test, the HCG index in the blood can clearly determine the length of pregnancy, so that the doctor can give an accurate due date, the due date refers to the fetus in the body for 10 months and is about to give birth.

However, the physique of each pregnant woman is different, if you give birth 1 or 2 weeks in advance, there is no problem, the fetus is also full-term, if you delay it a little 1 2 days, you don't have to worry too much, but if there is no sign of delivery by the expected delivery date, then you should do a caesarean section in time to avoid fetal hypoxia death.

Generally, the pregnancy is about 10 months, and if there is an aunt, it is basically impossible to get pregnant.

Generally speaking, the baby can be born in October when the baby is pregnant, otherwise, it will be a premature baby, and the child will be born before the full trembling branches, which may lead to the child's premature death or other pathologies, but for some reasons, it is necessary to let the baby come to the side in advance, so at least how long can the baby be born healthy?

Regarding the question of the general months of labor for pregnant women, pregnant women can calculate according to the last menstrual period of pregnancy or some ** tests in the first trimester. The expected date of delivery, that is, the date of expected delivery of the pregnant woman, is not the exact date of delivery, because it is difficult for every pregnant woman to accurately judge the time of conception, so it is medically stipulated that the expected date of delivery is calculated from the first menstrual period of the last pregnancy, and the entire pregnancy period is 280 days and 10 gestation months. During pregnancy, it is easy to have a miscarriage, so women should regularly go to the hospital for health tests and prenatal check-ups accompanied by their family members.

1. According to medical regulations, the expected date of delivery is calculated from the first day of the last menstrual period, and the entire pregnancy period is 280 days, 10 gestation months (each gestation month is 28 days).

2. The month of the last menstrual date is added by 9 or minus 3 to the number of months of the expected date of delivery. The number of days plus 7 is the expected date of delivery.

3. Generally, it is normal to give birth at 37-42 weeks.

1. The relationship between preterm birth and age: the preterm birth rate of pregnant women under the age of 20 or older than 35 years old has increased significantly, especially for those younger than 20 years old, and the incidence of preterm birth is 11 times that of the 20 and 34-year-old group.

2. The relationship between preterm birth and miscarriage history: the history of miscarriage, especially the history of cave sheds, repeated miscarriages, induced abortions, induced labor or re-pregnancy less than one year after miscarriage, has the greatest impact on pregnant women. Due to the varying degrees of damage to the cervix caused by abortion, cervical insufficiency is caused by inadequate cervical function, which increases the rate of preterm birth.

3. The relationship between fetal position and preterm birth: the incidence of preterm birth in breech presentation is 7 times that of the total maternal preterm birth rate.

4. The relationship between preterm birth and disease: pregnancy combined with acute infectious diseases and certain internal and surgical diseases, such as rubella, influenza, acute infectious hepatitis, acute pyelonephritis, acute cholecystitis, acute appendicitis, pregnancy-induced hypertension, heart disease, etc., can easily lead to preterm birth. Pregnant women with endocrine disorders, insufficient progesterone or estrogen, severe hyperthyroidism, diabetes, etc., can cause preterm birth.

Pregnant women with severe anemia can also be born prematurely due to insufficient oxygen supply to the uterus and placenta due to tissue hypoxia. Malnutrition in pregnant women, especially protein deficiencies and vitamin E and folic acid deficiencies, also contribute to preterm birth.

5. The relationship between preterm birth and living environment: engaging in manual labor, working too long and too tired can significantly increase the rate of preterm birth. Frequent mood swings or excessive mental tension can cause cerebral cortex dysfunction, increased catecholamine secretion, sympathetic nerve excitation and vasoconstriction, and premature birth.

Frequent sexual intercourse in the third trimester of pregnancy is a common cause of premature rupture of membranes. Smoking and excessive alcohol consumption in pregnant women are also strongly associated with preterm birth.
