When a woman is 36 weeks pregnant, she is already in the late stage of pregnancy. Late pregnancy women and fetuses will be prepared for future childbirth. At 36 weeks of pregnancy, a prominent feature of the fetus is that it will enter the womb. Fetal implantation is a very new term for many women. So what is fetal implantation? When does the fetus enter the womb? What does it feel like for a fetus to enter the womb? What are the characteristics?
1、 What is fetal implantation
If the biparietal diameter of the fetal head reaches below the pelvic entrance of the mother, it is considered that the fetal head is in proportion to the pelvic cavity, which is called fetal pelvic insertion. Indicating the possibility of vaginal delivery and completing the first step of the delivery process.
Generally speaking, the fetal position will not change after entering the womb, laying a good foundation for a smooth delivery. Due to the fact that the fetal head has already entered the pelvic cavity, pregnant women may experience frequent urination, constipation, and cervical dilation in the future, which are all normal. As the uterus enlarges and descends, it compresses the intestines and bladder, and the fetal head entering the pelvic cavity sometimes collides with the cervical opening, resulting in frequent urination, constipation, and cervical dilation. As long as there are no signs of water breakthrough, redness, or frequent contractions during labor, there is no need to worry. Maintaining a happy mood, walking in moderation, and keeping one's body in optimal condition are the most important.
2、 When does the fetus enter the womb
As the gestational weeks increase, pregnant women often feel tightness or occasional abdominal pain in the late stages of pregnancy, which is a normal phenomenon. It is a force that pushes the fetal head downwards, causing the fetal head to gradually descend. For the first childbirth, the time for the fetal head to enter the pelvis is generally around 36 weeks, accounting for 80% -90% of primiparous women, but there are still 10% -20% who wait until after delivery before entering the pelvis. Postpartum women often do not enter the pelvis until before or after labor. If the doctor has determined that there is no head in the womb, there is no need to overly worry about whether the fetal head enters the womb on time. Some primiparous women may also enter the womb after the onset of contractions. The change in fetal orientation (LOA or ROA) before the onset of uterine contractions is not clinically significant. Appropriately increasing the amount of exercise (mainly walking), while using a pregnant woman's abdominal belt to secure the abdomen and fetus, can help the fetus enter the womb as soon as possible.
3、 What does it feel like for a fetus to enter the womb
1. There is no special feeling when entering the pot, you may find that your stomach is lower.
2. There is a feeling of sagging in the lower abdomen and a slight pain.
3. Lower body swelling and pain, clearly feeling like the baby is moving down.
4. The feeling of a fetus entering the womb is like something suddenly falling from your body.
5. After the fetal head enters the pelvic cavity, the uterine floor will descend.
4、 Six major symptoms indicate that the fetus has entered the womb
Symptoms of pelvic entry: 1. Changes in abdominal shape
Entering the pelvis represents the downward movement of the child's fetal position. Pregnant women will find that their belly shape will change, and your belly will look a little lower, like changing from a watermelon to a grapefruit. And this is something that almost every baby, whether it's a boy or a girl, will experience, indirectly breaking the folk saying of 'having a man at the top and a woman at the bottom'.
Symptom 2 of pelvic entry: a feeling of sagging in the lower abdomen and pain in the genital area
After the fetal position moves downwards, it will compress the female genitals and sacrum, and the mother will naturally feel a downward force and slight tenderness in the genitals. So after the fetus enters the womb, women should pay attention to rest and avoid lifting heavy objects. To prevent premature rupture of membranes caused by excessive force of abdominal descent.
Symptom 3 of pelvic entry: Irregular contractions are more frequent
Due to the stimulation of the genital area and other reproductive organs caused by fetal descent, false contractions often occur, so pregnant mothers do not need to be overly nervous. It is worth mentioning that if the fetus experiences regular contractions after entering the womb, it is necessary to seek medical attention for delivery.
Symptom 4 of pelvic invasion: frequent urination
The bladder that stores urine is located in the lower abdomen, on the anterior wall of the uterus. When the fetus enters the uterus, the uterus continues to enlarge and compress the bladder, leading to a weakened function of the bladder in storing urine and resulting in frequent urination in women. Of course, this type of urinary frequency is not accompanied by painful urination or bloody urination. If a mother feels pain or even blood during urination in addition to frequent urination, she should be alert to urinary tract infection.
Symptom 5 of pelvic entry: relaxed breathing and improved appetite
Due to the descent of the fetus into the womb, the pressure on the diaphragm, lungs, heart, and stomach is reduced. These organs located relatively higher will gradually recover their function, so you will feel relaxed breathing and eating more.
Symptom 6: After the fetal head enters the pelvic cavity, the height of the uterus will decrease
At 9 months of pregnancy, the uterine fundus is at the highest point of pregnancy, with the central part located around the second transverse finger below the xiphoid process. At the end of the 10th month of pregnancy, when the baby's head descends to the pelvis, the uterine floor will return to its height at the end of the 8th month of pregnancy, but the uterine floor is much wider than at that time.
This article provides a detailed introduction to the relevant knowledge about fetal implantation. If you are a woman in the late stage of pregnancy and want to give birth to your baby naturally, it is best for you to carefully understand the relevant knowledge of fetal delivery. This will allow you to easily grasp the situation of your fetus in the womb and determine whether you can successfully give birth naturally.
