When Does Fetal Movement Start in the Second Trimester? Normal vs. Abnormal Patterns

Updated: 2025-09-06 · Reading time: ~5 mins · Fetal movement guide

Fetal movement is one of the most important signs of life during pregnancy. Most moms-to-be begin to clearly feel movements during the second trimester (18–25 weeks). But when exactly does it start, what’s considered normal, and when should you be concerned?

When does fetal movement begin?

• First-time moms: Usually feel the first movements around 18–20 weeks.
• Experienced moms: May notice movements earlier, around 16–18 weeks, as they’re more familiar with the sensation.
• Individual differences: Slim moms may feel movement earlier, while those with more body fat may notice later.

What normal fetal movement looks like

• Early movements feel like “fluttering” or “gentle tapping.”
• As pregnancy progresses, movements become stronger and more regular.
• Movements are often easier to notice at night or when resting quietly.
• After 28 weeks, fetal movement becomes more predictable—typically at least 30 times in 12 hours.

 Abnormal fetal movement to watch for

• Too little movement: Fewer than 10 movements in 12 hours or a noticeable decrease should prompt medical attention.
• Sudden absence of movement: Could signal fetal distress or lack of oxygen.
• Excessive movement: A sudden spike in activity may also be an early warning sign of distress.

‍ Doctor’s advice

From 28 weeks onward, moms are advised to count fetal movements daily. The common method: record movements for 1 hour in the morning, afternoon, and evening, then multiply the sum by 4 to estimate 12-hour activity. Any unusual changes should be checked by a doctor promptly.
