Baby Movements at 21 Weeks: When to Seek Help

What if I have not felt movement yet?
First movements are often noticed between 16 and 24 weeks, sometimes after 20 weeks in a first pregnancy. If you have never felt movement by 24 weeks, tell your midwife. Contact your maternity team sooner if you are worried.
What can affect what I feel?
A placenta at the front of the uterus can make movements harder to notice. It does not prove that reduced movement is harmless. A website cannot assess your baby's wellbeing.
Can a baby sleep for 12–14 hours without moving?
No. That claim in the previous version was incorrect. RCOG describes fetal sleep periods as usually 20–40 minutes, rarely exceeding 90 minutes. These figures are not instructions to wait before seeking help.
Do I need a particular number of kicks?
There is no universal normal daily count. Learn your baby's pattern and follow any individual monitoring advice from your care team. A home Doppler cannot confirm that your baby is well.
