Many people have misconceptions about entering the pelvic cavity and entering the birth canal, but in reality, there is a significant difference between the two. Today, let me explain the difference between entering the pelvic cavity and entering the birth canal.
Entering the pelvic cavity refers to the situation where the fetus is in the late stage of pregnancy, with its head facing downwards, buttocks facing upwards, and the whole body curled up, surrounded by amniotic fluid and membranes. In this way, in the maternal pelvis, the fetal head enters the pelvic cavity through the entrance, thereby fixing the position of the fetus. When the fetus enters the womb, many mothers experience a feeling of tightness and pain in the abdomen, and the symptoms of frequent urination and urgency become more pronounced after the fetus enters the womb. Mom's body may also experience symptoms such as edema and constipation, which are caused by compression on the bladder.
The so-called birth canal refers to the passage through which a fetus is delivered, which includes the bone birth canal and the soft birth canal. When a fetus enters the birth canal, it indicates that the baby is about to be born.
Simply put, the fetus enters the pelvic cavity. Entering the pelvic cavity is a preliminary preparation for entering the birth canal, laying the groundwork for vaginal delivery. In the late stage of pregnancy, around 36 weeks, some fetuses have already entered the womb. The birth time of each fetus is different. The probability of natural childbirth success is high in the late stage of pregnancy, which is close to full-term. But it cannot be ruled out that having a baby in the womb for several weeks may not necessarily lead to labor. And when the fetus enters the birth canal, it indicates that it is about to be born, or in other words, during the birth process, when it is displayed as entering the pelvic cavity, it will gradually enter the birth canal.
