The early or late start of the fetus depends on

When pregnancy reaches the end stage, pregnant women and their families are very worried, because the fetus and the mother will face many risks in the end stage. For example: placental aging, turbid amniotic fluid, and high blood pressure in pregnant women. Therefore, when pregnant women reach the due date, they are eager to give birth to their children as soon as possible. Therefore, it is very important to start the fetus early, mid and late. What are the factors that determine whether a fetus starts to develop early, mid or late? Related content is as follows:

1. The thickness of the mother's abdominal cavity. For expectant mothers with thick abdomen, they may feel that the baby's fetal movement will be slightly slower. For pregnant women with thin abdomens, when the baby moves in the late pregnancy, you can even see a bulge outside the abdomen.

2. How much amniotic fluid does a pregnant woman have? The amniotic fluid of pregnant women is the guardian of the fetus. It blocks many external influences on the baby. Similarly, it will also affect the expectant mother's feeling of the baby's fetal movement. Pregnant mothers with more amniotic fluid will be slower to feel the baby's movements.

3. Mother’s sensitivity. Everyone has different sensory sensitivities. Some expectant mothers are very sensitive to pain, so they can keenly feel even the slightest fetal movement.

4. Placental maturity. The early, middle and late start of fetal development is related to the maturity of the placenta, and the maturity of the embryo is related to the blood supply and oxygen production of the fetus. If the placenta ages too early, it may lead to premature birth or fetal intrauterine hypoxia.

Why are most babies not born on their due date?

We mentioned earlier that the due date is calculated based on the pregnant woman's expected date of delivery. Although there is no problem with this time, it is impossible to know when the sperm and egg actually combine, because only when the sperm and egg combine successfully can it be said to be pregnant. Therefore, the due date is actually just an approximate time, not the exact time when the baby is born. Some pregnant women may make mistakes in their due date, which can also cause inaccurate delivery date. According to a survey, less than 50% of pregnant women give birth on their due date.
