The so-called due date is the expected date of birth, that is, the approximate date of the baby's birth, and the expected date of birth is only based on the last menstrual period of the pregnant mother to estimate, which there are some errors, after all, each pregnant mother's menstrual cycle is not 100% punctual, to completely figure out the date of the baby's birth basically can not be done.

So, the due date is the approximate date of the baby's birth, and only about 5 percent of fetuses will be born on the due date, the rest is before or after the due date, and in the medical said, as long as it is born between 38-42 weeks of gestation, is a normal situation.

Pregnant women past their due date, why the delay in birth?

1. The expected date of delivery is all calculated with the day of the pregnant mother's last menstrual period, and the whole pregnancy is 280 days, each month is calculated in 28 days, so it's the 10th month of pregnancy. But in fact this is not particularly accurate, some pregnant mothers menstruation is 30 days, some are 35 days, if the menstrual cycle is longer, then most of the baby will be born after the due date; if the menstrual cycle is shorter, then the baby in the due date before the birth of the possibility of great.

2. The physical condition of the pregnant mother will also affect the accuracy of the due date, for example, some pregnant mothers are physically weak, some pregnant mothers have a bad uterine environment, some pregnant mothers have a slow cervical ripening, etc., which indirectly affect the due date to be early or pushed back.

3. Even if the mother's menstrual cycle is punctual, the expected date of birth may not be accurate, but also depends on the time of the embryo, generally speaking, the successful fertilization of the embryo is a regular time, but if the embryo is late, the expected date of birth is not allowed. Originally, the due date would be more accurate according to ovulation, but most women don't know when their bodies ovulate, so they follow the last menstrual period.

4. If the fetus enters the womb late, or the umbilical cord is wrapped around the neck, it will also affect the time of birth. The so-called pelvic is the head of the fetus down into the pelvic cavity, this action will be completed between 36-38 weeks of pregnancy, if the pelvic late or early, will affect the expected date of delivery.

What should a pregnant woman do if her fetus is delayed after her due date?

As mentioned earlier, the baby born on the day of the due date is actually not much, as long as the birth in the 38-42 weeks of pregnancy are normal, so pregnant mothers after the due date, the fetus has not been born yet, there is no need to be particularly anxious, only after the 42nd week of pregnancy is an abnormality, that is, the expiration of the pregnancy. Of course, these situations in the birth of the doctor will pay special attention to the time, after 40 weeks of the fetus is not yet born, the doctor will let the pregnant mother pay more attention to, but also will guide the pregnant mother to carry out some of the methods to promote the birth of the baby.

Note: This is not a drug, but a way to get the body to receive the signal to start the labor.

For example, pregnant mothers can walk around the house more or climb stairs to help stimulate uterine contractions.

For example, pregnant mothers can eat some hawthorn and drink some chrysanthemum tea, which can soften the cervix and stimulate uterine contractions.

For example, pregnant mothers can press and pinch the RT while bathing, which can stimulate uterine contractions.

Tell me about my experience

My baby was just two weeks past his due date, the baby was developing well, and everything was normal in the labor and delivery test, but it was just slow to come out. In the 40th week of pregnancy, the doctor said that 41 weeks before the start to strengthen the physical exercise, let me walk more, do more housework, I did do, but the baby is still not willing to come out.

Until 42 weeks of pregnancy, the baby finally started, but it hurt me for more than ten hours and I couldn't get it down. After the doctor's examination, it turned out that the umbilical cord was wrapped around the neck for two weeks, plus the umbilical cord was too short, the baby couldn't rotate normally, and the baby could only be born by caesarean section.

So, when a pregnant woman arrives at her due date, the fetus is not launched first, don't be anxious, be sure to be on time, listen to the doctor's guidance arrangements.
