How many months of pregnancy does the fetus enter the pelvis?

The growth and development of each fetus is different, so the actual time of entry into the pelvis is also different. When the pregnancy reaches 36 weeks, it is necessary to check whether the fetus has entered the calf in order to prepare for the successful birth of the baby. So at how many months of pregnancy does one start to enter the uterus? Let’s all follow and learn about it.

Around 36 weeks of pregnancy, the fetus's head will enter the mother's pelvis, that is, the biparietal diameter of the fetus in the head position will enter the lower part of the mother's pelvic canal and be symmetrical with the pelvis. This situation is called "fetal head entering the pelvis". It is a signal sent by the fetus that it is ready to come and it is also the first step in the process of normal delivery.

According to a survey, 80-90% of first-time babies will have the sign of engagement at 37-38 weeks of pregnancy, that is, the baby's head fully enters the mother's pelvis. The time of engagement of the pelvis can be early or late. For a small number of people, the pelvis will not engage until just before delivery, while for some people, signs of engagement will appear as early as 33 or 34 weeks of pregnancy. For some people, it is not easy to engage the pelvis until just before delivery.

For pregnant women who are pregnant with their second child, most of the time, the signs of calving will not appear until the night before delivery. Whether the baby's head can fully enter the pelvis is an important indicator for doctors to determine whether natural delivery can be chosen. However, according to a survey, most pregnant women who have no signs of engagement at 38 weeks of pregnancy can give birth successfully, and only a small number of them need caesarean section. Therefore, pregnant mothers do not need to worry too much about the early, middle or late time of engagement.

It should be made clear that the insertion of the fetus into the pelvis does not mean that the pregnant woman will give birth immediately. It is just a sign of delivery. For women who are pregnant for the first time, the baby will come 2-3 weeks after the fetus enters the uterus. For pregnant mothers who are pregnant with their second child, they will directly enter the delivery stage after the fetus enters the uterus. The calving is only a signal that the fetus is about to arrive, not a signal for delivery. Pregnant mothers should deal with it calmly.
