How many months does the fetus enter the pelvis? What are the differences between pregnant women and pregnant women after the fetus enters the pelvis?

We all know that after a woman becomes pregnant, the fetus will continue to grow in the mother's belly. As the months go by, the fetus will gradually mature and enter the pelvis to wait for delivery. Due to the different physical conditions of pregnant mothers, the time when the fetus enters the pelvis may be earlier or later. So when does the fetus enter the pelvis? Let's take a closer look!

When does the fetus enter the pelvis?

The time when the fetus enters the pelvis may be before delivery, there is no fixed time, but a normal fetus can enter the pelvis normally between 37 and 40 weeks. If it exceeds 42 weeks, it is considered an overdue pregnancy and the pregnant mother needs to seek help from a doctor in time. The performance of fetal engagement in the pelvis will also vary in multiparous women and first-time pregnant women. Multiparous women will give birth quickly after the fetus enters the pelvis because they have experienced delivery in the birth canal, while the first-time pregnant women may take a long time after the fetus enters the pelvis. This is caused by the different physical constitutions of the pregnant women and will not cause harm to the fetus.

After the baby enters the pelvis, you will find that your lower abdomen is falling, and you may even feel pain in your genitals. Avoid lifting heavy objects at this time to prevent the abdomen from falling too hard and causing premature rupture of the membranes. Also, as the fetus moves downward, the height of the mother's uterus decreases, and the shape of the belly changes. It may be like a watermelon at first, but now it is like a grapefruit. In addition, the appetite has improved, but the urination frequency has increased. You have just gone to the toilet, but you have to go to the toilet again. The fetal movement will also become slower and feel less agile.

What are the differences between pregnant women after the fetus enters the pelvis

1. The shape of the pregnant mother's belly has changed. It used to be like a big watermelon, but it became a grapefruit after the fetus entered the pelvis.

2. The appetite has improved. The fetus has moved downward, and the pregnant mother's stomach has also breathed a sigh of relief. Food is no longer so hard on the stomach. The appetite feels better and the appetite has increased greatly.

3. Breathing becomes smoother. While the stomach relaxes, the lungs also relax greatly. Pregnant mothers will feel that their breathing becomes smoother and they are no longer so short of breath.

4. The fundus of the uterus has dropped, and the height of the uterus of the pregnant mother will drop to a height of about 32 weeks.

5. The back and waist hurt more. After the fetus enters the pelvis, the pressure on the lower abdomen of the pregnant mother is greater, so the pregnant mother will feel more back pain, and even feel bloated and painful in the perineum.

6. The pubic pain becomes more painful. Pregnant mothers who already had pubic pain before the fetus entered the pelvis will feel that it is more painful now. The pressure from the fetus causes the pubic bones to separate more, so it will feel more painful.

7. Constipation and frequent urination become more obvious. These are normal changes after the fetus enters the pelvis.

8. False contractions are frequent. In order to prepare for delivery, the pregnant mother's body is also working hard. The pregnant mother must learn to distinguish between true contractions and false contractions. False contractions are painless and will pass after a rest. True contractions are really painful and will get more and more painful. Resting is useless.

How long will it take for the fetus to be born after entering the pelvis?

In the third trimester, when the fetus grows to about 36 weeks, it will enter the pelvis, and then it will take one to two weeks to be born, but if it is the first time, the fetus will be born soon after the pelvis. But not all pregnant women have obvious feelings, so it is best to go to the hospital for examination, which will help with production and discover risks.

Factors that affect fetal engagement

① The pregnant mother’s abdominal muscles are very elastic and her belly is relatively tight, making it more difficult for the fetus to descend.

② The pregnant mother's usual sitting posture causes the fetus to lie in the occiput posterior position, so it is difficult to enter the pelvis.

③ If the fetus is relatively large or the entrance of the pregnant mother's pelvis is relatively narrow, it will affect the time it takes for the fetus to enter the pelvis.

Finally, some fetuses may be in a transverse or breech position, which prevents the fetus from entering the pelvis, which may require the pregnant mother to have a caesarean section. Of course, the final method of delivery is still determined by the doctor's judgment.
