Will the fetus enter the pelvis when lying down?

A woman's body undergoes completely different changes after pregnancy. Some pregnant women often feel weak and like to lie down and rest. There shouldn't be any big problem in the early stages of pregnancy, but if the delivery is approaching and the pregnant woman doesn't like to exercise. It will affect the changes of the fetus in the body. If you choose to give birth naturally, it will be more difficult. Will the fetus enter the pelvis when lying down?

Will the fetus enter the pelvis if you lie down frequently?

It will have an impact. After pregnant women enter the late stage of pregnancy, it is not recommended to lie on your back for a long time, because the weight of the uterus will compress the large veins in your back, slowing down the blood flow back from the legs to the heart. However, once you fall asleep, you can no longer control your posture. If you wake up lying flat, it's probably because your body needs you to change your posture, so you wake up. Generally speaking, lying on the left side is the best sleeping position for pregnant women. While there's no real downside to sleeping on your right side during pregnancy, sleeping on your left side can be beneficial for you and your baby because it increases blood and nutrient flow to the placenta and helps your kidneys remove waste and fluids more efficiently. This, in turn, will reduce swelling in areas such as your ankles, feet, and hands. If you train yourself to sleep on your left side early on, it will be easier to fall asleep when your belly gets bigger. Therefore, it is best not to lie in bed for a long time in the late pregnancy, because doing so will affect the fetus's entry into the pelvis. Pregnant women in the late stages of pregnancy need to walk more and climb stairs more often, which will help with pelvic engagement and natural delivery. We say that the most suitable fetal position for normal delivery is the cephalic position, that is, the fetus's head is facing down and the buttocks are facing up. The main reason for this posture is the effect of gravity, and the weight of the fetus's head is relatively larger. If pregnant women often lie down or sit, the fetus will not be able to adjust its position to enter the pelvis. If the pregnant woman can move appropriately, it will help the fetus adjust to a head-down position and then enter the pelvis smoothly.

The feeling of the fetus entering the pelvis

In medicine, in order to make delivery smoother, the fetus's body position needs to be consolidated. Then, the fetus's head will enter the pelvic cavity through the mother's pelvic entrance. This is called engagement. So for new mothers, what does it feel like when the fetus enters the pelvis?

Decreased uterine height: Expectant mothers may find that their belly has moved down a little, which is called decreased uterine height. Decreased uterine height means that around the 9th month of pregnancy, the fundus of the uterus will be at its highest point during pregnancy, and when the fetus enters the pelvis, the fundus of the uterus returns to the height of the 8th month of pregnancy.

A feeling of falling in the lower abdomen: Many pregnant mothers often feel a tightness and pain in the abdomen, and feel that the fetus in the belly is descending.

Pain in the genitals: As the fetus moves downward, it will compress the pregnant mother's genitals and sacrum. The pregnant mother will feel a downward force and slight tenderness in the genitals.

Irregular uterine contractions are more frequent: False uterine contractions are common due to the stimulation of the genitals and other reproductive organs by the falling fetus. Pregnant mothers do not need to be too nervous. It is worth mentioning that if regular uterine contractions occur after the fetus enters the pelvis, you should seek medical attention for delivery.

Frequent urination: The symptoms are obvious, and at the same time, symptoms such as edema, constipation, and low back and leg pain will also be aggravated. When the fetus enters the pelvis, the uterus continues to grow and compresses the bladder, causing the bladder's ability to store urine to weaken, resulting in frequent urination in pregnant mothers. If the pregnant mother feels pain when urinating or even has blood in her urine in addition to frequent urination, she should be alert to the possibility of urinary tract infection.

Easier breathing and better appetite: As the fetus's position drops after entering the pelvis, the pressure on the diaphragm, lungs, heart, and stomach is reduced. The organ functions in these areas gradually recover, so pregnant mothers will feel that they can breathe more easily and eat more.
