Reasons for exceeding the due date, what to do if the fetus exceeds the due date

Some mothers do not have the situation of giving birth when the due date arrives, which makes the mother very anxious and wonders if there is an accident in the baby in the belly. Today, by reading the following article, let's learn about the reasons for exceeding the due date? What should I do if my due date is exceeded?

In this way, mothers will be able to prepare in advance.

Reasons for exceeding the due date.

1. Mother's differences: Each mother's physical condition is different, and there will be differences in physique, which will lead to discrepancies in the calculation of the due date, especially the advance or postponement of the mother's ovulation day.

2. Unclear menstrual date: Mothers do not remember the actual time of their last menstrual period when they are checked, which will also affect the accuracy of the estimate.

3. Other factors: If the mother does not remember the time of her last menstruation, the doctor will also use the method of B ultrasound to help estimate, but there will be some differences in the development of each baby, which is also the reason for the inaccurate due date, which may be estimated too early.

4. For mothers who pay too much attention to rest during pregnancy and do not exercise properly, it will affect the development of the baby. At the same time, abnormal baby development can also affect the due date.

Precautions for delivery after the expected date of delivery.

1. Relax: The due date is not the exact time of delivery, and it is normal to give birth 2 weeks before and after the due date.

2. Continue the prenatal examination: when you go to the hospital for examination, give the doctor the information that can estimate the birth time of the baby such as the examination report of the early pregnancy, and check the number of weeks of pregnancy again.

3. Strengthen examination: If you have not given birth to the due date, then the time of birth of the baby will not be very far, mothers should pay attention to their own situation at any time, and go to the hospital in time if there are signs of childbirth.

4. If you have not yet given birth by the due date, you must go to the hospital. Because the placenta will age after term, the baby may experience hypoxia and other conditions, which will threaten the baby's life and health.

When a mother is pregnant, it is not a very serious thing to exceed the due date, and there is no need to worry too much. Only half of all babies in the world will be born on the day of their due date, so don't be too anxious. Normal daily routines and appropriate exercises that help you give birth can ensure a smoother delivery.

It is a normal physiological phenomenon that the baby is not born after the due date, and it is normal for the fetus to be born two weeks before or after the due date. Not every fetus will be born on the day of delivery, as long as there is no abnormality in the due date, the fetal heart rate monitoring is normal, and the amniotic fluid volume is normal in color ultrasound. The specific reason why the baby has not given birth after the due date is not clear, and it may be related to the large fetus or the late conception.

If you do not give birth after a week of the due date, you can hang oxytocin to induce birth.

With the development of medical level, more and more women will calculate the due date after pregnancy, prepare in advance, and wait for "unloading". However, there are also some pregnant women who have reached the due date but the baby has not yet been born. So, why is the fetus past its due date?

What should I do if my baby is past its due date?

If the fetus exceeds the due date, it is most likely caused by the lack of exercise of the expectant mother. When the fetus matures, it secretes a hormone that enters the mother's bloodstream, prompting the mother's pituitary gland to secrete oxytocin, initiating contractions and labor. After labor, the fetus actively looks for a suitable meridian in the mother's pelvis to go out.

As labor progresses, the fetus will gradually descend under the impetus of bursts of uterine polarity and symmetrical contractions and abdominal muscle contractions, and when the fetal head reaches the pelvic floor, the fetus will be successfully delivered with the contraction and promotion of the pelvic floor muscles.

When the pregnant woman's exercise is reduced, the fetus will lack the power of passive movement given by the mother, and the initiative is poor, and it cannot actively secrete sufficient hormones to the mother. The mother's lack of exercise, lack of muscle elasticity, and insufficient amount of oxytocin can not initiate uterine contractions, delaying labor, thus causing post-term pregnancy. In addition, post-term pregnancy is also related to the function of the fetal adrenal cortex, or if the mother is an advanced maternal age for the first time, it is also likely to cause an overterm pregnancy.

In addition, an imbalance in the ratio of estrogen to progesterone and some genetic factors can also lead to post-term pregnancy.

The main reason for not giving birth after the due date is that pregnant women exercise too little during pregnancy, resulting in poor fetal motivation and insufficient hormone secretion. Therefore, we say that if you want to prevent you from not being able to give birth after the due date, the most important thing is to exercise regularly. Pregnant women can strengthen their exercise, upright exercise can promote the fetus into the pelvis, and at the same time, it can also exercise the pelvic floor muscles and increase labor force.

However, it should be noted that you should be very careful at this time, and remember not to be too intense.

If the due date is postponed to 14 days or later, the pregnancy is clinically called. At this time, because the placenta of some pregnant women will begin to age, the fetus will appear hypoxic asphyxia, which is more harmful to the child, so at this time, you should go to the hospital for a detailed examination and follow the doctor's arrangement. At the same time, the interval between examinations should be shortened, the doctor should be contacted at any time to inform the intrauterine fetal movement, and the amniotic fluid volume should be followed up by ultrasonography.

If there are no abnormalities, the pregnancy can continue under close supervision.

After the fetus enters the mother's pelvis at a certain stage, it will be ready to give birth, but during this period of time, it is necessary to adjust the schedule and rest, calculate the expected date of delivery with the help of the doctor, and make full preparations, so as to cope with the arrival of the baby in an orderly manner. Of course, some babies are not born for a long time, and they are past the due date. What happens if the baby is past the due date?

1. Walking is the most suitable way to exercise in the third trimester. Walking can breathe fresh air, and at the end of pregnancy, walking can help the fetus descend into the pelvis, relax the pelvic ligaments, and prepare for childbirth. When walking, you should walk around and talk to your child, and listen to the singing of birds and the noise of crickets with him.

2. Prenatal gymnastics is very popular abroad, which can not only promote the fetal head into the pelvis, but also increase the toughness and elasticity of the pelvic floor muscles.

3. You can often hear the doctor say to the expectant mother who has passed the due date and has not moved: "Go climb the stairs." "Climbing stairs can exercise the muscle groups of the thighs and buttocks, which can help the fetus enter the pelvis and make the first stage of labor come quickly.

4. Drug induce. A series of tests and monitoring are performed to assess the condition of the fetus and the function of the placenta before the drug is induced to make a decision. If the ultrasound measurement finds that the fetus is too large or the neck is already quite soft on digital inspection, it can be considered to start giving birth earlier.

If the cervix is mature, the placenta is functioning well, and the amniotic fluid volume is normal, you can wait a little longer.

After 2 weeks of due date, accompanied by fatigue, irritability, or occasional abdominal pain. In prenatal examination, pay attention to the fetal movement count, and generally the cumulative number of fetal movements is not less than 10 times within 12 hours is normal. If it is less than 10 times in 12 hours or decreases day by day, it indicates that the placenta is inadequate and the fetus is hypoxic.

The test measures the amount of estriol in the urine and the ratio of estriol to creatinine over a 24-hour period to understand uterine placental function.

1. Dystocia. If the post-term pregnancy reaction lasts for too long and the function of the placenta does not deteriorate, then the fetus will continue to develop and grow in the womb of the expectant mother, and finally form a macrosomia (that is, the fetus weighs more than kilograms and is more than 55 cm long), and eventually the baby's head will become stiffer, the shoulders will be widened, and the risk of pregnancy diseases such as fetal intracranial hemorrhage and maternal birth canal injury will also be increased.

2. Cause fetal death.

If the mother-to-be has an overdue pregnancy for too long, the greater the chance of developing overmaturity syndrome. This type of fetus is prone to death. Even if they are born, their health is much worse than that of a normal child, and they often die of dehydration, anemia, and lung infections.

3. Prolongation of labor time.

The fetus that exceeds the due date is generally larger, and the fetal skull becomes stiffer and the shoulders are wider, the fetal skull is not easy to deform during delivery, the fetal head is difficult to descend, and the delivery time will be longer.

Is there a baby who has not moved after the due date? At this time, you must be very worried, why is there no movement yet? Will there be any problems with the fetus? Do you want to go for a caesarean section?

Let's first understand how the expected date of delivery is calculated, the algorithm of the expected date of delivery is the month of the date of the last menstrual period plus 9 or minus 3, day plus 7 method to calculate, the normal pregnancy period is generally about 280 days, but in fact, the expected date of delivery such an algorithm will not be very accurate. If a pregnant woman has taken contraceptive pills before pregnancy or has other reasons that cause the menstrual cycle to be prolonged, her ovulation period will also be extended, the time to conception will also be extended, and the expected date of delivery will also be extended.

About 10% of pregnant women will not give birth after the due date, and if they do not go into labor two weeks after the due date, it is called an overdue pregnancy.

Post-term pregnancies may be caused by too much progesterone, too little estrogen, or genetic remorse. Don't think that the longer the baby is in the mother's belly, the better, the overdue pregnancy has a certain harm to the fetus and the pregnant woman, this is because the placenta will slowly age after the time, and the baby will not be able to provide sufficient oxygen and nutrition, and the baby will grow thinner and thinner, malnourished. In addition, it may suffocate the fetus, and may also cause dystocia and increase the mortality rate of the fetus at birth.

Although not every pregnant woman will have the above dangers, it is better to be careful in everything, and human life should not be played.

If the pregnant woman exceeds the expected date of delivery for a week, she can go to the hospital for a B ultrasound examination to see if the placenta is aging, if there is no aging, don't worry, relax, wait patiently, or do a small amount of exercise every day, but remember not to go far, to prepare supplies for childbirth at any time; If the placenta is found to be aging on ultrasound, the pregnant woman should be hospitalized immediately and ask the doctor to arrange for an induction of labor or a caesarean section.

The due date is an estimate, many pregnant women do not give birth on time during pregnancy and childbirth, and may give birth within two weeks before or after the due date, so if you are still in the stool during this time period, don't worry, go to the hospital for a check-up, and follow the doctor's instructions. But if you have exceeded this time, then you should be careful and take necessary measures to terminate the pregnancy if necessary.

Suggestions: Because the placenta is the link between the mother and the baby, the fetal metabolites are also excreted from the body by the placenta transmitted to the mother. The placenta has a certain lifespan, and after two weeks of the due date, it gradually ages and begins to decline in function.

As the fetus grows and matures, not only does the oxygen demand increase, but also the tolerance to hypoxia gradually decreases. Even if the placental function is good, but the post-term pregnancy is also prone to dystocia, which is due to the fetus is larger, heavier than the full-term baby, the fetal skull is hard, the fetal head deformation ability is poor during labor, it is easy to occur pelvic head disproportionality, abnormal fetal head position, and uterine contraction weakness.

It is recommended that if you are not at ease, you can go to the hospital to wait for delivery! When appropriate, your doctor can help you deliver your baby early and prevent death.

Nowadays, many pregnant women give birth to babies beyond their due dates. If the due date has passed, you should go to the hospital in time to wait for delivery to prevent the sudden launch from bringing danger to the mother and the child.

If a pregnant woman gives birth beyond the due date, she generally has to get up and move at this time, and then she has to take an inducing injection, and if it is not possible, she may have to discuss and formulate a new birth plan.

If a pregnant woman gives birth beyond the due date, she must have a regular prenatal checkup. Special attention needs to be paid to all aspects of the body's reactions. Moreover, pregnant women have not yet given birth beyond the due date, such problems are common, but they should be treated with caution.

In your case, the pregnancy time has to be reversed, but it is not too accurate compared to ordinary people.

According to what you said, if you are not pregnant, you should have a menstrual period around September 3rd, and 14 days forward from this date is the approximate ovulation day, which is August 19th. Now look at your B-ultrasound results, and it is basically the same.

The due date is 266 days based on the actual embryo's development time in the womb, starting from August 19, 2011, and the expected date of delivery is May 10, 2011.

If there's anything you don't understand, just ask me again, hehe.
