What should you know?
Fetal movement is often first noticed around 18–20 weeks and sometimes earlier in a subsequent pregnancy. An anterior placenta and individual factors can delay perception.
As pregnancy progresses, each baby develops a recognizable activity pattern. A meaningful reduction compared with that usual pattern matters more than a universal number.
Common symptoms and signs
- Early movement can feel like fluttering or gas
- Active periods alternate with fetal sleep
- Movement quality changes as space becomes tighter but should not stop
- A clear reduction requires assessment
Diagnosis and the role of ultrasound
Reduced movement may lead to heart-rate assessment, cardiotocography and, when indicated, ultrasound of growth, fluid, movement and Doppler flow. Home Doppler devices do not replace professional assessment.
- Cardiac activity and observed movement
- Growth and estimated fetal weight
- Amniotic fluid volume
- Placenta and Doppler when indicated
Treatment and next steps
Follow the movement-counting method provided by your maternity team. If movement is clearly reduced, contact maternity care the same day rather than waiting for a routine visit.
When is urgent care needed?
- Marked reduction or absence of movement
- Reduced movement with bleeding, pain or leaking fluid
- Severe headache, visual symptoms or significant swelling
