Causes of early pelvic insemination

Early engagement of the fetus will affect the fetal breathing, and engaging the fetus too early will affect the delivery of the pregnant woman, so everyone should pay attention to the time when the fetus engages the pelvis, and then be prepared for delivery when the fetus engages the pelvis. The time of entry into the pelvis is generally about 2 weeks before the expected date of delivery. At this time, pregnant women will experience symptoms such as uterine dilation and frequent urination, and amniotic fluid rupture may also occur. Pregnant women adjust their emotions and prepare for delivery.

Causes of early fetal pelvic entry

The time when each fetus enters the pelvis is different. Some enter the pelvis a month before delivery, while others enter the pelvis when giving birth. Just let it go and don't worry too much.

If the biparietal diameter of the fetal head reaches below the entrance of the mother's pelvic cavity, the fetal head and pelvis are proportional, which is called "fetal engagement". This indicates that vaginal delivery is possible and the first step of the delivery process has been completed.

Generally speaking, the fetal position will not change after entering the pelvis, which lays a good foundation for a smooth delivery. Since the fetal head has entered the pelvis, the pregnant woman may experience frequent urination, constipation, cervical distension, etc. This is normal. As the uterus grows and descends, it compresses the intestines and bladder. The fetal head entering the pelvis sometimes collides with the cervical opening, so frequent urination, constipation, cervical distension, etc. There is no need to worry as long as there is no labor phenomenon such as water breaking, spotting, frequent uterine contractions, etc. The most important thing is to maintain a happy mood, move around moderately, and keep your body in the best condition.

The entry of the fetus into the pelvis does not mean that delivery will occur immediately, but the entry of the fetal head into the pelvis may induce uterine contractions due to pressure on the cervix, so before the due date, the activity time should be appropriately controlled.

Early pelvic engagement does not necessarily lead to premature birth. Generally speaking, the fetal head enters the pelvis about 2 weeks before the due date, but for some women, it enters the pelvis earlier, which is normal. Some give birth on the same day the baby enters the pelvis, while others take a month or two. Some people do not experience symptoms of diaphragm compression because the fetus is small or the fetal head enters the pelvis early, which has nothing to do with premature birth.

What are the symptoms of pregnancy?

As your pregnancy draws to a close, the baby in your belly is already quietly preparing for birth. He (she) will wait for the opportunity with his (her) head down, buttocks up and whole body curled up, surrounded by amniotic fluid and fetal membrane. Before delivery, the first thing the fetus is forced to do is to put its head through the mother's pelvic inlet into the pelvic cavity so that its body position is consolidated. This is what is medically known as "pelvic entry". It can be said that pelvic floor is the prelude to childbirth.

When the fetus enters the pelvis, many pregnant women often feel a tightening and heavy pain in their abdomen, and think that the fetus in their abdomen is descending, so they will rush to the hospital in a hurry. In fact, this situation is not a real sign of labor. The main differences are that first, the duration of uterine contractions is short, often less than half a minute; second, the contractions are irregular and relatively weak. Therefore, it is often called "false labor". But no matter what, the pelvis entering the pelvis means that delivery is approaching, and pregnant women can make all kinds of preparations based on this signal to welcome the arrival of the baby.

The fetus enters the pelvis between the 36th week of pregnancy and the onset of labor pains. Generally, the first baby may enter the pelvis earlier. Although the fetus has entered the pelvis, it does not mean that labor pains will occur immediately. Sometimes it may take several weeks before labor pains occur. Sometimes, even if the baby has not entered the pelvis, there is no need to worry, because the entry into the pelvis may be completed after the labor pain. If it is the second child, the fetus usually enters the pelvis before labor pains begin.
