If the due date does not come out, why is the due date inaccurate? What is the reason why I have not

Self-test first and then go to the hospital for a check-up.

Although the due date has passed, if it has not exceeded 2 weeks, the expectant mother does not need to worry too much, which is a normal situation.

Because the due date is not the actual date of delivery, it can be affected by factors such as the age of the expectant mother, maternity history, the length of the menstrual cycle, and the difference in the number of days in different months. If the fetus has developmental problems, or the expectant mother has some kind of disease, it will also widen the gap between the two.

According to scientists, only about 5% of expectant mothers will give birth on the due date, and the remaining 95% of expectant mothers will give birth two weeks before and after the due date.

What should I do after my due date?

Expectant mothers can usually do more exercise, such as taking a walk with their husband, which is not very intense and helps to give birth. If you are physically able, you can also squat and walk by holding your hands on the edge of the table and standing with your feet steady.

Slowly bend your knees and move your pelvis down. The legs are naturally separated by their knees until they are fully flexed. Then, slowly stand up and push your feet up firmly until your legs and pelvis are erect, repeating several times.

In addition, expectant mothers should strengthen prenatal check-ups and pay attention to monitoring fetal movements, because fetal movements are the best means for expectant mothers to monitor the development of the fetus in utero. Once you find that the fetal movement is significantly reduced or increased, you must go to the hospital for examination in time.

However, if the expectant mother has collapsed the due date for 2 weeks and there is still no sign of delivery, the pregnancy should be terminated immediately, otherwise the expectant mother and the baby will be in danger, and the more days exceeded, the higher the risk.

Because with the increase of gestational age, the placenta's ability to feed will become worse and worse, the fetus will get much less nutrients and oxygen, and the fetus will be in a state of chronic hypoxia. In addition, if the fetus stays in the uterus for too long, the fetal skull bone suture will gradually close, and the plasticity will be reduced, which will easily lead to dystocia or cesarean section for the expectant mother.

The due date is calculated according to 28 days per menstrual cycle, so if your previous menstrual cycle is shorter than 28 days, the child will come out early, if your previous menstrual cycle is longer than 28 days, it is likely to be longer than the due date, and there is no problem if you exceed the due date, but it is best not to enter 41+, because there is a high probability that the amniotic fluid will be reduced, the child will be hypoxic and asphyxic, etc., after the due date, special attention should be paid to fetal heart rate monitoring, as well as the time of fetal movement, if the fetal movement is significantly reduced, go to the hospital immediately!

The due date is 90% accurate, and if there are some cases of premature birth, then there may be some factors, such as physical factors, and some emotional excitement.

It is mainly related to the way of calculation, sometimes it is calculated according to the menstrual cycle, but some women will have irregular menstruation and will have a large error. It may be that the child has not yet reached maturity.

The normal pregnancy cycle is 40 weeks, but after 37 weeks of pregnancy, the fetus is full-term and may be born at any time. Since every woman experiences different situations during pregnancy, the timing of childbirth is also different.

The calculation of the due date is calculated according to the last menstrual period, because the time of menstruation is different for each person, so there will be some differences in the due date, and it is not normal to be born on the day of the due date. It's normal to produce a pure mountain one to two weeks before and after the due date, so don't worry too much. As long as you are pregnant, do the tests that need to be done and keep abreast of the situation.

During pregnancy, it is necessary to do a good examination, so that you can better understand the development of the fetus and better judge the time of delivery. Especially in the third trimester of pregnancy, various examinations are indispensable. After the due date, if there are some abnormalities in the body, you need to go to the hospital for examination in time.

When it is time to give birth, if there is no abnormality in the body and the examination is normal, then it is necessary to wait patiently and follow the doctor's instructions. If there is an abnormality in the body, you need to be hospitalized for delivery. And it is also necessary to determine the production method according to the specific inspection situation.
