23 Weeks Pregnant: What to Expect With Weight Gain, Baby Movement, and Getting Ready

At 23 weeks pregnant, your baby is roughly the size of a large mango and your body is in full gear—but nobody warns you that the second trimester’s most intense phase is only just beginning.

Most people focus on the milestone checkboxes: the kicks you’re feeling, the weight creeping up on the scale, the sudden Braxton-Hicks that make you pause mid-sentence. What gets overlooked is how much is actually happening underneath—organ systems maturing, your baby hearing your voice, your own body signaling it needs more fuel and more rest than you expected.

This week, we’re breaking down what’s normal at 23 weeks (and what’s not), what your care team should be watching, and how to actually prepare for the third trimester without spiraling.

23 Weeks Pregnant: What’s Happening With Your Baby

This week, your baby is about the size of a large mango — roughly 11 inches long and just over a pound. They’re starting to look like a real, fully-formed baby, even though there’s still a lot of growing to do.

The organs are doing serious work right now. The lungs are developing the tiny air sacs called alveoli, and the pancreas is producing its own insulin. None of it is ready for the outside world yet, but the groundwork is being laid.

Here’s the part that gets me every time — your baby can hear you. Real sounds are getting through: your voice, music, even the rumble of daily life. Those little ears are working. The AAP notes that babies exposed to voices and language in the womb show recognition of familiar sounds after birth, which is why reading to your bump.

Their sense of touch is developing too. They can feel their own face, grasp the umbilical cord, and respond to movement. There’s a whole sensory world opening up in there — which is a big leap from where things were back at 22 weeks pregnant.

Skin is still translucent and thin, and the fat layers that will give your baby that soft, round newborn look haven’t filled in yet. That comes later.

On the viability front — 23 weeks sits right at the edge of where survival outside the womb becomes possible with intensive medical support. It’s not a comfortable thing to think about, but it matters to know. Next week marks a significant medical threshold, and you can read more about that in our 24 weeks pregnant guide.

Right now though, your baby is exactly where they should be. Growing, hearing, moving. Becoming.

Weight Gain at 23 Weeks: What’s Normal and What Isn’t

Can we just say it? The number on the scale can mess with your head in a way almost nothing else does during pregnancy.

Here’s what I know: weight gain in pregnancy is not one-size-fits-all, and comparing yourself to anyone else — or to some chart you found online at 2am — is going to make you feel worse, not better.

That said, having a general sense of what’s expected does help. Most people with a pre-pregnancy BMI in the “normal” range gain somewhere between 1 and 5 pounds in the first trimester, then roughly a pound a week from there. By 23 weeks pregnant, you might be looking at somewhere between 12 and 15 pounds total — but your OB’s guidance matters far more than any general number.

Starting weight changes everything. If you began pregnancy underweight, you may need to gain more. If you started with a higher BMI, your provider may recommend a smaller total range. Carrying twins? The whole calculation shifts again.

For a deeper look at how weight typically breaks down across all three trimesters, the pregnancy weight gain by trimester guide covers it in detail.

The AAP recommends that weight gain concerns during pregnancy always be evaluated in the context of overall nutrition and fetal growth — not the number alone.

So what’s actually worth flagging? Sudden, rapid weight gain — especially paired with swelling in your hands or face — can be a sign of preeclampsia and needs a call to your OB the same day. Gaining very little or losing weight in the second trimester is also worth a conversation.

Your body is doing something extraordinary. The weight is not the enemy. But staying in communication with your provider about it? That’s just good care.

Baby Movement at 23 Weeks: Kicks, Flutters, and Patterns

Here’s the thing nobody fully prepares you for: once you feel those movements, you will spend the rest of your pregnancy half-listening for the next one.

At 23 weeks pregnant, most people describe movement as something between a gentle nudge and a definite thump. The wispy butterfly flutters from a few weeks ago are giving way to real, unmistakable kicks — sometimes strong enough to see from across the room.

You might notice your baby has a rhythm already. Active after you eat. Quiet in the morning. Going wild at 11pm just when you’re trying to sleep. That’s not random — that’s paying attention to your baby’s development.

The AAP notes that fetal movement patterns become more established and consistent during the second trimester as the baby’s nervous system matures — which is exactly why changes in that pattern matter later on.

You don’t need to do formal kick counts just yet. That typically starts around 28 weeks. But right now, getting familiar with your baby’s normal? That’s the whole job.

What’s worth a call to your provider: if movement suddenly feels significantly less than usual, or you go a full day without feeling anything at all. Trust that instinct. You know your baby’s rhythms better than anyone.

It’s also worth knowing that movement can feel different depending on how your placenta is positioned, your body type, and whether this is your first pregnancy. Some people feel everything intensely; others have to lie still and really focus. Neither means anything is wrong.

Common Symptoms and Body Changes at 23 Weeks

Here’s the honest truth: the second trimester is supposed to be the “easy” one, and for a lot of people it genuinely is better than the first. But that doesn’t mean it’s comfortable.

Your back is working overtime right now. Your center of gravity has shifted, your belly is pulling forward, and your muscles are doing their best to keep up. A pregnancy pillow at night and gentle movement during the day — even just a short walk — can make a real difference.

Braxton-Hicks contractions might be showing up too. They feel like a tightening or hardening across your belly, and they’re practice runs — your uterus rehearsing for labor. They’re irregular, they fade when you move or drink water, and they don’t hurt the way real contractions do. If they become regular or painful, always check with your provider.

Heartburn is another one nobody warns you about enough. Your growing uterus is literally pushing up against your stomach. Eating smaller meals, staying upright after eating, and skipping spicy or acidic food in the evening can help take the edge off.

Swelling — especially in your feet and ankles by the end of the day — is completely normal at this stage. Elevating your feet when you can and staying hydrated actually helps more than cutting fluids back.

You might also notice round ligament pain, leg cramps, or skin stretching and itching as your bump grows. All of it is your body doing exactly what it needs to do.

One thing worth knowing: The AAP recommends staying physically active during pregnancy when there are no complications, as movement supports circulation and can ease common discomforts like back pain and swelling.

If you want to see how these symptoms continue to shift, 28 weeks pregnant brings its own wave of changes — good to know what’s ahead.

Prenatal Care: Tests, Appointments, and Screenings at 23 Weeks

Honestly, the number of appointments and tests can feel overwhelming. But here’s what I want you to know — each one is giving you a clearer picture of how you and your baby are really doing.

The glucose screening test typically happens between 24 and 28 weeks, so if you’re 23 weeks pregnant, your provider may bring it up at your next visit or schedule it soon. It’s a one-hour blood draw that checks how your body is processing sugar — nothing scary, just important information.

Growth scans around this time help confirm your baby is measuring on track. Your care team is looking at things like fluid levels, placenta position, and whether your baby’s growth is following a healthy curve.

Blood pressure checks happen at every appointment, and they matter more than they might seem. Sudden increases can be an early sign of preeclampsia, which is why your provider takes that reading every single time you come in — not as a formality, but as real monitoring.

When it comes to what to actually talk to your care team about: bring up anything that feels off. Swelling that came on fast. Headaches that won’t quit. Vision changes. These aren’t things to wait on.

It’s also a good time to ask about kick counts, if your provider hasn’t mentioned them yet. The AAP recommends that pregnant people track fetal movement in the third trimester as a way to monitor baby’s wellbeing — your care team can walk you through exactly how to do it.

And if you’re starting to think ahead to feeding, bottle feeding positions is worth a read whenever you’re ready. Getting familiar with the basics now takes one thing off your plate later.

Preparing for the Third Trimester and Beyond

Here’s the thing nobody tells you: the third trimester arrives faster than you expect. One day you’re navigating the middle stretch, and suddenly you’re googling hospital parking and wondering if you’ve left everything too late.

You haven’t. But now is a good time to start moving on a few things.

If your hospital offers a tour, book it. Walking the space before you’re in labor makes a real difference. You’ll know where to park, what the rooms look like, and you’ll feel less like a stranger when the time comes.

A birth plan is worth drafting — not because everything will go according to it, but because the process of writing it helps you figure out what actually matters to you. Pain management preferences, who’s in the room, cord clamping, skin-to-skin. Get your thoughts down. Then hold them loosely.

Childcare planning takes longer than most people anticipate. Waitlists for daycares can stretch six months to a year in some areas. If that’s on your horizon, start the conversation now — even if your return-to-work plans aren’t fully settled yet.

Mental readiness is harder to check off a list, but it matters just as much. If you’re already feeling anxious about birth or what comes after, that’s worth naming — to your partner, your provider, or someone you trust.

The weeks between now and 34 weeks pregnant move quickly. Small steps now — a booked tour, a drafted plan, one childcare call — mean you’re not scrambling later.

You don’t have to have everything figured out. You just have to keep moving forward, one week at a time.

Nutrition and Self-Care at 23 Weeks

Here’s something nobody warns you about the second trimester: you’re hungrier than you expected, more tired than you thought you’d be, and somehow still trying to function like a normal person. That’s a lot to carry.

Your body is working hard right now. Around 23 weeks pregnant, most people need roughly 300–350 extra calories a day — not a dramatic amount, but enough that skipping meals will catch up with you fast.

Focus on protein, iron-rich foods, and healthy fats. Think eggs, lentils, salmon, avocado, Greek yogurt. The AAP recommends that pregnant people consume at least 200mg of DHA daily to support fetal brain and eye development — fatty fish like salmon and sardines are a good natural source.

Foods worth limiting: high-mercury fish, unpasteurized cheeses, deli meats (unless heated through), and anything that’s been sitting out too long. Your immune system is already working differently right now — you don’t need extra risk.

Sleep is getting harder, and that’s real. Left-side positioning takes pressure off major blood vessels and helps circulation to your baby. A pillow between your knees and one behind your back can make a real difference — a full-length pregnancy pillow designed for this shift in sleep geometry is one of the things that actually earns its place on the bed.

Stress management sounds like a wellness buzzword until you’re lying awake at 2am replaying your to-do list. What actually helps: shorter lists, honest conversations, and giving yourself permission to do less than you think you should.

Movement helps too — even a 15-minute walk. Not for fitness. Just to remind your nervous system that you’re okay.

Frequently Asked Questions

Is 23 weeks too early to feel my baby moving regularly?

No. By 23 weeks, most pregnant people are feeling regular, predictable fetal movement—though the timing and intensity vary widely depending on placenta position, your body awareness, and your baby’s activity patterns.

If you’ve been feeling movement for weeks, you may notice it’s becoming more consistent and stronger. If you’re just starting to feel distinct kicks now, that’s also completely normal.

How much weight should I have gained by 23 weeks pregnant?

For someone with a pre-pregnancy BMI in the normal range, roughly 12 to 15 pounds by 23 weeks is typical—but this varies based on your starting weight, metabolism, and how much you gained in the first trimester.

Your OB’s guidance for your specific situation matters far more than any general number. If you have concerns, bring them to your next appointment rather than comparing yourself to online charts.

What does a kick count mean and when do I start tracking at 23 weeks?

Kick counts are a way to monitor your baby’s activity and well-being by noting how long it takes to feel 10 distinct movements. Most providers recommend starting formal kick counts around 28 weeks, though you can certainly begin tracking patterns informally now if it gives you peace of mind.

At 23 weeks, the goal is just to get familiar with your baby’s typical activity—when they’re usually most active, how strong the movements feel, and whether patterns seem consistent day to day.

Is it normal to have cramping and Braxton-Hicks contractions at 23 weeks?

Yes, Braxton-Hicks (practice contractions) and occasional cramping are common in the second half of pregnancy, including at 23 weeks. Braxton-Hicks feel like a tightening across your belly and are typically painless.

If cramping is severe, persistent, accompanied by bleeding or fluid leakage, or doesn’t ease with rest and hydration, contact your provider. Otherwise, these sensations are your uterus practicing for labor—annoying but not dangerous.

Can my baby survive if born at 23 weeks?

Survival is possible at 23 weeks with intensive neonatal care in a hospital setting, though outcomes vary significantly based on access to specialized equipment and expertise. Viability thresholds differ by region and facility.

At 23 weeks, your baby is at the edge of medical viability—it’s not a comfortable topic, but understanding it can help you make informed decisions if complications arise. This is an important conversation to have with your care team early.
