Pregnancy is really a wonderful process. Thinking about the new life in the womb is growing slowly, the happiness of being a mother-to-be will be born. However, the fetus in the mother’s stomach is very dishonest, always want to move, in this case, the fetal position is very difficult to fix. Especially when the fetus is still small, it is impossible to fix. So we not only have to ask, how many months of pregnancy can we fix the position of the fetus? This is the question we want to understand today. Fetal position refers to the position of the fetus in the mother’s body, and the correct position of the fetus in the mother’s uterus should be head down and buttocks up. Fetal malposition can cause varying degrees of difficulty and danger in labor. Before the 7th month of pregnancy, the position of the fetus is difficult to fix because of the relatively large amount of amniotic fluid and the small size of the fetus, which has a large range of motion in the uterus. If fetal malposition is detected before the 7th month of pregnancy, it is more likely that it can be adjusted under the guidance of the doctor at this time. If the malposition is detected too late, especially after 34 weeks of pregnancy, then a cesarean section should be considered. The position of the fetus usually starts to fixate at the end of the 6th month and into the 7th month or so. So at 7 months, you need to go for a labor and delivery check to see if the fetal position is normal. Normal fetal position is that the head of the fetus is bent over, with the occipital bone in front, and the head is the first to extend into the pelvis during delivery, which is called “cephalic pre-disclosure” in medical terms, and this kind of fetal position is usually more smooth. However, although some fetuses are also head down, but the head of the fetus from bent over to tilted or occipital bone in the back, it belongs to the fetal position is not correct. As for those deliveries in which the buttocks are exposed first (breech position), or the feet or legs are exposed first, or even the arms are exposed first (transverse position), etc., the fetus is even more malpositioned. In such cases, attention must be paid not only to check the position of the fetus on time, but also to correct it, and if it is found late and cannot be corrected, then the only option is to have a cesarean section.
