When will the second baby's fetal position be fixed

For pregnant women in the late stages of pregnancy, the fetal position must be paid close attention to, because it is closely related to the method of delivery. If the fetal position is relatively correct, natural delivery can be chosen. However, if the fetal position is not correct, then delivery via caesarean section is required. The fetal position will be fixed within a certain period of time. So, when will the fetal position be fixed?

1. The role of fetal position examination

Through a series of examinations in the late pregnancy, it can be basically determined whether the fetal position is normal or not. If the expectant mother's fetal position is found to be abnormal, it can be corrected; fetal position is also one of the bases for choosing the delivery method.

Fetal position refers to the posture of the fetus in the mother's body. The correct posture of the fetus in the mother's uterus should be head down and buttocks up. The posture of the fetus in the mother's womb before birth is very important. It is related to whether the pregnant woman will have a normal delivery or a difficult delivery. In a normal delivery, the head of the fetus should enter the vagina first. Many fetuses enter the vagina with their heads tilted upwards, which is also a malposition of the fetus. Malposition of the fetus is very harmful to both the fetus and the mother.

2. What is the normal fetal position?

The normal fetal position is the anterior occipital position, which is an inverted position, which is what doctors usually call the head position. This position is most conducive to normal delivery. The head will be tilted towards the chest as much as possible, so that the occipital bone of the fetal head can help the fetus pass through the birth canal quickly. The occipital bone of the fetal head is close to the front half of the mother's pelvis.

3. When is the fetal position fixed?

Generally speaking, the fetal position is constantly changing during the early and middle stages of pregnancy, and at the end of the sixth month and the seventh month, the fetal position will slowly begin to stabilize. Therefore, you must have a prenatal check-up at seven months to check whether the fetal position is normal. If it is not normal, you can correct the fetal position with the help of a doctor at that time.

The posture of the fetus in the uterus before birth is very important, and is directly related to whether the fetus can be delivered naturally. If the fetal position is not correct, it may easily lead to dystocia for the mother during delivery, which is very dangerous for both the mother and the fetus. If this happens, fetal position surgery or caesarean section is often required, and natural delivery can no longer be performed.
