What are the differences between the fetal movements of normal babies and abnormal babies? What are the fetal movements of normal babies like?

We all know that after a woman reaches a certain stage of pregnancy, the baby will gradually develop and grow and move frequently, which is what we call fetal movement. In different periods, fetal movements are also different. Fetal movements are generally more frequent in the second trimester. So what is the difference between the beating of a normal fetus and an abnormal fetus? Let’s take a closer look below!

The difference between abnormal fetal and normal fetal movements

Time of initial fetal movement

Normal fetal movements generally appear at 16-18 weeks, while abnormal fetal movements will appear later, and it may take about 20 weeks before pregnant women can feel fetal movements.

Activity of fetal movement

Fetal movement has its own pattern. Normal fetal movement may be frequent during the day and quiet at night, or there may be very little fetal movement during the day and more active fetal movement at night. Abnormal fetal movements are irregular, slow, and infrequent.

Amplitude of fetal movement

Normal fetal movement will be relatively large, and pregnant women will feel that the fetal movement is very powerful. The fetal movement of an abnormal fetus is small and extremely weak. If the pregnant woman is careless, she may not feel the fetal movement for a lot of time.

What does the problematic fetal movement look like?

1. Fetal movement is too late

Generally speaking, fetal movement will be more frequent at the end of the 12th week. Multiparous women will feel fetal movement at 15-16 weeks, and first-time mothers will feel fetal movement at 18-20 weeks. If you still can’t feel fetal movement at 20 weeks, you must go to the hospital for consultation. You need to determine whether there is something wrong with your own feelings or whether the fetus is really not moving.

2. Abnormal fetal movement

If the pregnant mother has a high fever, the pregnant mother sleeps in an improper position that puts pressure on the fetus, and the amniotic fluid decreases, the fetus will be hypoxic and reduce fetal movement.

If the pregnant mother's abdomen is hit by external force, serious trauma, uterine pressure is reduced, the umbilical cord is knotted, etc., the fetal movement will accelerate and suddenly stop.

What are normal fetal movements like?

Normal fetal movements are regular, rhythmic, and do not change too much.

1. At 16-20 weeks, the fetal movement is concentrated near the belly button, which is not obvious and very slight. Sometimes it swims like a small fish, sometimes it dances like a butterfly, and sometimes it purrs.

2. At 20-35 weeks, fetal movement is closer to the stomach and is obvious. The fetus will make various large-scale movements such as punching, kicking, and rolling.

3. After 35 weeks, the fetal movement is very powerful. If the baby enters the pelvis early, the fetal movement will become less. If the baby enters the pelvis early, the fetal movement will still be a lot.
