In the late stages of pregnancy, the fetus is already preparing for a smooth birth, presenting a head down, hip up, and curled up position in the uterine cavity, and allowing its head to enter the pelvic cavity through the mother's pelvic entrance. However, some pregnant women want to know what happens when the fetus comes out after entering the pelvic cavity?
Generally speaking, the fetus will not come out again after entering the pelvic cavity, which is the prelude to delivery. However, if a pregnant woman discovers that the fetus has come out again after entering the pelvic cavity, it may be because the pelvic cavity of the pregnant woman is relatively flat, that is, the anterior posterior diameter of the pelvic entrance is shortened, and the transverse diameter is normal, which makes it difficult for the fetus to enter the pelvic cavity. Even if it enters the pelvic cavity, it may still come out.
The flat pelvis of pregnant women prevents the fetus from entering the pelvic cavity, which may lead to changes in the fetal position, such as anterior occipital, posterior occipital, or transverse occipital. Therefore, pregnant women need to undergo prenatal examination during delivery to determine whether vaginal delivery is possible based on the size and position of the fetus. If not, it is necessary to switch to cesarean section delivery.
Most pregnant women who have a baby in the womb will feel a sensation, such as tightness and pain in the abdomen, and the entire time of entering the womb is very short. If pregnant women want to confirm whether they have entered the womb, they can go to the hospital for abdominal ultrasound to confirm. After the baby successfully enters the womb, it will further compress the bladder, causing symptoms such as frequent urination and edema to worsen.
