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.
