Contact your doctor if your baby’s movements become noticeably weaker or stop, especially if this is different from their usual pattern. Don’t wait until the next day or try to reassure yourself with at-home checks: contact the healthcare professional overseeing your pregnancy and follow their advice.
Fetal movements during pregnancy are an important guide, but every baby has their own pattern of activity, which can change. This article explains which changes to look out for and why, if you’re unsure, it’s better to get a medical assessment than rely on a universal norm.
| Situation | Gestational age or threshold | What to do |
|---|---|---|
| Movements become more noticeable | 24–28 weeks | Note the usual pattern of movements |
| No movements | After 22 weeks | Contact your doctor |
| No signs of activity | 3–4 hours after 28 weeks | Eat something sweet and lie on your left side; if that doesn’t help, contact your doctor |
| Sudden decrease in activity | Over 12 hours | Contact your doctor |
| No movements at all | Throughout the day | Contact your doctor |
- 24–28 weeks the stage when movements usually become more noticeable
- 22 weeks the point after which no movements are a reason to contact your doctor
- 28 weeks the point from which an approximate pattern of activity develops
- 3–4 hours a period with no signs of activity after 28 weeks, after which you can try lying on your left side and contact your doctor if there are still no movements
- 12 hours the period over which a sudden decrease in activity warrants contacting your doctor
How do fetal movements change as pregnancy progresses?
Movements usually become more noticeable between 24 and 28 weeks, and by around 28 weeks your baby develops their own pattern of activity. These time frames are a guide, not a schedule: what matters more is noticing the pattern of movements that is usual for your baby.
How the sensations change
As your baby grows, movements may feel different: smooth rolls may replace sharp kicks. But movements should continue every day, even in late pregnancy—feeling that there is less room for your baby does not mean they have stopped moving.
An anterior placenta can soften the sensations, while slim women are usually more sensitive to movements. So compare your baby’s activity first and foremost with their usual pattern, not with what other pregnant women feel. If movements change suddenly or become noticeably less frequent, contact your doctor.
Why is the usual pattern more important than counting individual kicks?
The usual pattern matters more than the number of individual kicks because a noticeable change in activity can be significant even if movements have not stopped. From 28 weeks, it’s helpful to pay regular attention to when and how your baby usually moves, so you can compare what you observe with their individual pattern rather than simply counting kicks.
Watch for changes
When assessing movements, consider both their frequency and their character: have the kicks become weaker, or do the movements seem unusual? After 28 weeks, movements are usually noticeable, and an approximate pattern of activity can help you spot changes. No movements at all throughout the day, a sudden decrease in activity over 12 hours, or a change in the character of the movements are reasons to contact your doctor.
- Usual pattern: Note when your baby is most active and compare new observations with that pattern.
- Sudden decrease over 12 hours: Contact your doctor, even if you can still feel occasional movements.
- Unusual movements: Tell your doctor how their character has changed, not just how strong the kicks are.
Counting movements can help you notice a change, but it does not replace medical assessment if activity has changed noticeably. Don’t put off contacting your doctor so you can keep counting kicks or wait until the movements become impossible to distinguish: discuss any marked changes with your doctor.
When does an absence of fetal movements call for contacting a doctor?
No movements after 22 weeks of pregnancy, complete stillness throughout the day, or a noticeable decrease in your baby’s usual activity are reasons to contact your doctor without waiting until the next day. These changes need medical assessment: you can’t tell what caused them based on sensations alone.
What to do after 28 weeks
If your baby shows no signs of activity for 3–4 hours after 28 weeks, you can eat something sweet and lie on your left side. This is a brief way to see whether movements appear, not a substitute for seeking medical help.
If movements don’t resume afterward, contact your doctor right away—don’t wait until the end of the day or put off assessment until your next scheduled appointment. If movements return but become noticeably less frequent or change in character, tell your doctor as well.
What can affect the sensations, and when are at-home checks not enough?
The sensations can be affected by the position of the placenta and your position, but neither quieter nor suddenly more active movements can, by themselves, rule out complications: a noticeable change in your baby’s usual activity needs a doctor’s assessment. Sensations also vary from woman to woman, so what matters more is noticing changes from the pattern of movements that is usual for your baby.
- Anterior placenta: When the placenta is at the front of the abdomen, movements may feel less intense.
- Lying on your back for a long time: The enlarged uterus can compress the inferior vena cava and trigger a vigorous response from the fetus. This response does not confirm that everything is fine.
- Sweet food or lying on your left side: These are not diagnostic checks of your baby’s wellbeing and do not replace contacting a doctor.
Don’t rely on self-monitoring alone.
If movements have not resumed after 3–4 hours of stillness, seek medical assessment rather than continuing at-home checks. External stimuli can change fetal activity, but you can’t tell on your own whether this is a response to the stimulus or a possible complication.
What should you tell your doctor if your baby’s activity changes?
If your baby’s activity changes, tell your doctor how far along you are, when you last felt movements, how long they were unusually quiet, and exactly what has changed. The milestones after 22 and 28 weeks are especially important: no movements after 22 weeks call for contacting your doctor, and from 28 weeks it’s helpful to track your baby’s usual activity.
Describe the change specifically: movements have become less frequent, were completely absent throughout the day, or changed in character—for example, you felt something different from what you usually feel. Say how long it has been since the last movement; if there have been no movements for 3–4 hours after 28 weeks, tell your doctor. It’s also important to mention no movements at all throughout the day and a sudden decrease in activity over 12 hours.
Tell your doctor if you’ve been lying on your back for a long time: in this position, the enlarged uterus can compress the inferior vena cava. Mention whether you tried lying on your left side after 3–4 hours without movements, and whether movements resumed. If activity does not return or is noticeably different from the usual pattern, don’t put off contacting your doctor.
