Is it normal to have faint fetal movements at five months of pregnancy?

Introduction
Generally, most expectant mothers begin to feel fetal movements after 18–20 weeks of gestation. However, there is considerable individual variation in this timing. In clinical practice, I have encountered cases where some mothers perceive distinct fetal movements as early as 16 weeks, while others—despite having reached 20 weeks (i.e., five months’ gestation)—still report no obvious sensation of fetal movement.
Fetal movement is a crucial indicator for expectant mothers to perform self-monitoring at home. Generally, most women begin to feel fetal movements after 18–20 weeks of gestation; however, there is considerable individual variation in this timing.
In clinical practice, I frequently encounter cases where some women perceive distinct fetal movements as early as 16 weeks, while others—despite having reached 20 weeks (i.e., five months’ gestation)—still report no clear sensation of fetal movement. Why does this occur?
First, maternal abdominal wall fat thickness plays a significant role: thinner women tend to perceive fetal movements earlier, whereas women with obesity—particularly those with excessive abdominal subcutaneous fat—are less sensitive to fetal movements.
Second, parity also strongly influences the timing of perceived fetal movements. Primiparous women (those experiencing their first pregnancy) typically recognize fetal movements later, commonly after 18–20 weeks. In contrast, multiparous women (those who have previously given birth) often perceive fetal movements earlier; some may even detect them as early as 14 weeks—especially if they are relatively slender.
Notably, the absence of obvious fetal movements at five months’ gestation alone should not be used to diagnose intrauterine fetal hypoxia. If routine B-mode ultrasound demonstrates normal fetal growth and development, along with favorable placental and umbilical cord blood flow parameters, this generally indicates no evidence of intrauterine fetal hypoxia.
