In week 23 many people feel their baby's movements more and more clearly, though they vary a lot — from gentle flutters to distinct kicks. There is no single pattern that fits everyone: what you feel depends on things like the position of the placenta, your body shape, and whether this is your first pregnancy. It is worth starting to observe your own rhythm instead of comparing yourself with descriptions online.
What to do in week 23
- Note the date of the first clear movement, if you haven't already.
- Set a daily reminder for a short note about movements.
- Record the times of day when movements are clearest.
- Prepare notes about contractions: when they appear and how they ease.
- Write down your questions about movements and contractions for the next visit.
When to start observing movements
First movements appear within a wide time window, and it is hard to name one right moment. If you haven't felt anything yet, mention it at your next visit — the staff will check that everything is progressing as expected for your week of pregnancy.
- Note in your app the date when you first felt a clear movement.
- Record the times of day when movements are easiest for you to notice.
- Pay attention to the character of the sensations: fluttering, bubbling, kicks.
- Don't compare the number of movements with descriptions online.
How to keep a movement diary without pressure
The diary is there to help you get to know your own baby, not to turn you into a form-filling machine. The simplest approach: one short note a day, at a time when you are resting and unhurried. Over time you will notice your typical rhythm — and that is exactly the knowledge that becomes useful if any doubt appears.
- One short note a day is enough — no counting or comparing.
- Note what you were doing when movements were clear: resting, a meal, lying down.
- Also record days when movements seem different than usual.
- Bring your notes to a visit if something concerns you.
Contractions and movements — what to note down before a visit
If you are having contractions this week, write down when they start, how long they last, and whether they ease when you change position. Observations like these are far more useful to a doctor than a general "my belly hurts." If contractions become regular or come with other symptoms, don't wait for the scheduled visit.
What to do when something worries you
If movements seem different than before, call your clinic, your midwife, or the labor and delivery ward and say plainly what worried you. Don't put it off until the scheduled visit and don't look for answers in a search engine. The staff will ask for details and decide whether a check-up is needed.
- Call the facility managing your pregnancy and describe what has changed.
- Say when you last felt movements clearly and what you were doing then.
- Don't wait until the next day to make contact if your concern is growing.
- Write down who you spoke with and what guidance you received.
- In a life-threatening situation, call the emergency number.
How to talk about movements at a visit
Bring your notes from recent days to the visit, even if they are very short. The doctor needs specifics: when movements are clear, whether anything about them has changed, and whether they come with other symptoms. Instead of judging whether there are many or few, describe your typical day.
- Say at which times movements are clearest for you.
- Describe whether anything has changed in recent days.
- Mention other symptoms: contractions, pain, weakness.
- Ask how to observe movements in the coming weeks.
- Write down the recommendations while still in the office.
When and where to observe movements
Movements are easiest to notice in quiet moments, for example when you are sitting or lying down after a meal. You don't need to do it at a fixed hour or react to every single sensation — the goal is to know your own rhythm. If you feel nothing at a given moment, come back to it later and ask the staff how to approach such situations.
- Choose one or two times of day when you have some quiet.
- Don't compare the number of movements with other people's descriptions online.
- Keep notes short: time of day, character of sensations, changes.
- Bring your notes to the visit instead of relying on memory.
Tip
Set a daily reminder in your app for one short note about movements — it is easier to keep the habit than to write whenever it comes to mind.
When to contact a doctor
- • If movements become clearly different from before or noticeably weaker, call your doctor or midwife the same day.
- • Bleeding or fluid leaking from the vagina requires contacting your healthcare facility.
- • Regular, intensifying contractions are a reason to call without waiting.
- • Fever with abdominal pain requires a consultation, not waiting until the next visit.
- • In a life-threatening situation, call 112.

Week 23 in detail
Week 23: how your baby is growing — Grapefruit
At twenty-three weeks your baby is about the size of a grapefruit (around 289 mm). The body is taking on newborn proportions, blood vessels are developing in the lungs, and the skin — though still wrinkled — is no longer translucent.
Development at week 23
- Body proportions close to a newborn's.
- Blood vessels are developing in the lungs.
- The skin is no longer translucent, still wrinkled.
Tip
Midwife's tip: wrinkled skin is a normal stage — your baby will plump it up with fat in the coming weeks.

Week 23: what's happening in your body
At twenty-three weeks you may feel Braxton Hicks contractions — so-called practice contractions — for the first time. Your uterus is 'rehearsing' for birth. They're usually painless, irregular, and fade when you change position.
Braxton Hicks — how to recognize them
- The belly feels hard and tight, but without strong pain.
- They're irregular and don't get stronger.
- They ease with rest or a change of position.
When it's NOT Braxton Hicks
- Contractions that are regular and intensifying, every 10 minutes or more often.
- Accompanied by bleeding or your water breaking.
- Severe, constant pain.
When to contact a doctor
- • Regular, intensifying contractions before week 37 require urgent consultation — it could be preterm labor.
Tip
Midwife's tip: learn to tell practice contractions from labor contractions — calmly tracking regularity is your best tool.

Week 23: Newborn proportions — what you can do today
Week twenty-three is a good time to learn to recognize contractions. Knowing the difference between practice contractions and labor contractions brings calm and confidence for the weeks ahead.
Your tasks for this week
- Notice whether contractions feel regular.
- Note their duration and frequency.
- If they're practice contractions — simply rest.
A simple rule
- Braxton Hicks: belly hard, painless, irregular.
- Labor contraction: regular, intensifying, with pain.
- In doubt? It's always better to check with your doctor.
Tip
Midwife's tip: when you feel your belly tighten, change position and drink some water — a practice contraction usually fades.
