Patient's question:
When is the fetus most active during the day? How many times is considered normal for fetal movement in a day?Doctor's answer:
Hello: At 20 weeks of pregnancy, most women can feel fetal movement, which is particularly noticeable at night. The period from 29 to 38 weeks is the most frequent time for fetal movement, which slightly decreases as the due date approaches.Excessive pregnancy can lead to a decrease in fetal movement. Generally, fetal movement occurs 3 to 5 times per hour, with approximately 30 to 40 movements in a 12-hour period.
Under normal conditions, fetal movement strength and frequency vary throughout the day. Morning counts are lower, while counts increase after 6 p.m., with the most active movement occurring between 8 and 11 p.m. This indicates that the fetus has its own sleep patterns, known as the fetal biological clock.
The strength and frequency of fetal movement vary greatly among individuals. Some may have up to 100 movements in a 12-hour period, while others may only have 30 to 40. Loud noises, bright light stimulation, and touching or pressing the pregnant woman's abdomen can all increase fetal movement.
