At 23 weeks pregnant, you are deep in the second trimester, which is often called the “honeymoon phase” of pregnancymostly by people who are not currently trying to roll out of bed with a growing belly. Your baby is getting stronger, your body is working overtime, and your hormones are still conducting a very dramatic orchestra. Some days may feel exciting and sweet. Other days may involve heartburn, back pain, emotional commercials, and wondering why your legs suddenly have opinions at 2 a.m.
Week 23 of pregnancy is a fascinating point. Your baby is becoming more responsive, more active, and more recognizable as the tiny human you will eventually meet. Meanwhile, your uterus is expanding, blood volume is increasing, your skin may be changing, and your digestive system may be moving at the speed of a sleepy turtle. Most symptoms at this stage are normal, but knowing what is expectedand what deserves a call to your healthcare providercan help you feel more confident.

How Many Months Is 23 Weeks Pregnant?
At 23 weeks pregnant, you are about five months and one week into pregnancy. Pregnancy is usually counted from the first day of your last menstrual period, so the “23 weeks” number includes roughly two weeks before conception actually happened. Biology loves a plot twist.
You are still in the second trimester, which runs from week 13 through week 27. Many pregnant people feel more energetic during this stretch than they did in the first trimester, but that does not mean week 23 is symptom-free. Your baby is growing quickly, your belly is more noticeable, and your body is adjusting in big and small ways every day.
Baby Development at 23 Weeks Pregnant
At 23 weeks pregnant, your baby is roughly the size of a large mango or grapefruit, though size comparisons are charmingly inconsistent depending on who is holding the fruit basket. On average, a baby at this stage may measure around 11 to 12 inches long from head to heel and weigh about 1 pound, though every baby grows at an individual pace.
Your Baby’s Movements Are Getting Stronger
One of the most exciting parts of being 23 weeks pregnant is feeling more regular movement. Those early flutters may now feel like taps, rolls, nudges, or tiny karate practice sessions. Your baby has more muscle coordination, and as the nervous system develops, movement becomes more purposeful.
Formal kick counting usually starts later in pregnancy, often around the third trimester, but noticing your baby’s usual activity pattern can still be reassuring. Some babies are most active after meals, when you lie down, or right when you are trying to sleepbecause apparently babies begin comedic timing before birth.
The Lungs Are Practicing for Life Outside the Womb
Your baby’s lungs are still immature at 23 weeks, but important development is happening. Tiny air sacs are forming, and the body is beginning to produce surfactant, a substance that helps keep the air sacs open after birth. The lungs are not ready to fully function on their own yet, but this week is part of the important groundwork for breathing later.
Skin, Fat, and Features Are Changing
Your baby’s skin may still look thin and wrinkled because there is not much body fat yet. Over the coming weeks, more fat will develop under the skin, helping your baby look less like a tiny wise professor and more like the squishy newborn you imagine.
Fine hair called lanugo may cover parts of the body, and the eyebrows and eyelashes continue to become more defined. The hands and feet are also developing unique ridges that will become fingerprints and footprints. Yes, your baby is already working on a personal signature style.
Your Baby Can Hear More Sounds
At 23 weeks pregnant, your baby’s hearing is becoming more advanced. Your baby may hear your heartbeat, digestive sounds, blood flow, and muffled noises from the outside world. Talking, singing, or reading aloud can be a sweet way to bond, even if your baby’s review of your singing voice remains unavailable.
Sleep Cycles Are Developing
Your baby is beginning to have more organized sleep and wake patterns. Rapid eye movement, or REM sleep, can occur around this stage. That does not mean your baby is dreaming about nursery decor, but it does suggest that the brain and nervous system are developing in increasingly complex ways.
Common Symptoms at 23 Weeks Pregnant
Pregnancy symptoms at 23 weeks can vary widely. Some people feel strong, energetic, and surprisingly comfortable. Others feel like their body has installed 47 new software updates overnight without permission. Both experiences can be normal.
Back Pain and Pelvic Discomfort
As your uterus grows, your center of gravity shifts. Add hormone-softened ligaments, extra weight, and posture changes, and your lower back may start filing complaints. Back pain at 23 weeks pregnant is common, especially after standing for a long time or sleeping in an awkward position.
Supportive shoes, gentle stretching, prenatal yoga, warm compresses, and a pregnancy pillow may help. Avoid heavy lifting when possible, and bend with your knees rather than your waist. Your back deserves better than being treated like a folding chair.
Round Ligament Pain
Sharp or pulling pains on one or both sides of the lower belly can happen when the round ligaments stretch to support the growing uterus. This discomfort may appear when you stand quickly, roll over in bed, cough, sneeze, or move suddenly.
Round ligament pain is usually brief and harmless, but severe, constant, or worsening abdominal pain should be checked by a healthcare provider.
Heartburn and Indigestion
Pregnancy hormones relax smooth muscle, including the valve between your stomach and esophagus. That relaxation is helpful in some areas and deeply annoying in others. The result may be heartburn, acid reflux, burping, or feeling full after only a few bites.
Eating smaller meals, staying upright after eating, limiting spicy or greasy foods, and drinking fluids between meals rather than during large meals may help. Ask your provider before using antacids or acid reducers, especially if you need them often.
Constipation and Bloating
Progesterone slows digestion, and iron in prenatal vitamins may add to constipation. To help keep things moving, aim for fiber-rich foods such as fruits, vegetables, beans, oats, and whole grains. Drinking water and walking regularly can also support digestion.
If constipation becomes painful or persistent, talk with your healthcare provider. Do not start laxatives or herbal remedies without medical guidance, because “natural” does not always mean “safe during pregnancy.”
Leg Cramps
Leg cramps, especially at night, are common in the second trimester. They may be related to circulation changes, muscle fatigue, dehydration, or pressure from your growing uterus. Stretching your calves before bed, staying hydrated, and gently flexing your foot during a cramp may help.
Call your provider right away if one leg becomes swollen, red, warm, or painful, especially in the calf. That can be a warning sign of a blood clot and should not be ignored.
Swelling in Feet and Ankles
Mild swelling in the feet and ankles can happen because pregnancy increases blood volume and fluid retention. Resting with your feet elevated, wearing comfortable shoes, staying active, and drinking enough water may help.
However, sudden swelling of the face or hands, swelling with a severe headache, vision changes, or pain in the upper right abdomen can be a warning sign of preeclampsia. Contact your healthcare provider immediately if these symptoms occur.
Skin Changes
At 23 weeks pregnant, you may notice stretch marks, darker nipples, a dark vertical line on the belly called the linea nigra, or patches of darker facial skin called melasma. These changes are linked to pregnancy hormones and increased pigment production.
Sunscreen can help reduce melasma from becoming more noticeable. Stretch marks are partly genetic, so creams may help with itching and comfort, but they cannot always prevent marks from appearing. Pregnancy skin has its own agenda.
Breast Changes
Your breasts may feel larger, heavier, or more sensitive. Some people notice colostrum, a yellowish early milk, leaking from the nipples. This can be normal. A supportive bra and soft breast pads may help if leaking becomes inconvenient.
Headaches
Headaches may happen because of hormone changes, dehydration, stress, lack of sleep, hunger, or posture. Drinking water, eating regular meals, resting, and using cold or warm compresses may help.
A headache that is severe, sudden, persistent, or accompanied by blurred vision, dizziness, swelling, or high blood pressure symptoms should be treated as urgent. Pregnancy headaches are common, but not all headaches are casual visitors.
Vaginal Discharge
An increase in thin, milky, mild-smelling vaginal discharge is common during pregnancy. However, call your provider if discharge becomes green, yellow, foul-smelling, bloody, watery, or is accompanied by itching, burning, pelvic pain, or fever.
Hormones at 23 Weeks Pregnant
Pregnancy hormones are doing essential work at 23 weeks, even if they sometimes make you cry over a dog food commercial. The major hormones involved include progesterone, estrogen, relaxin, human placental lactogen, and prolactin.
Progesterone: The Great Relaxer
Progesterone helps maintain the uterine lining and supports pregnancy. It also relaxes smooth muscle, which can help prevent early uterine contractions. Unfortunately, smooth muscle also exists in the digestive tract, which is why progesterone can contribute to constipation, bloating, and reflux.
Estrogen: Growth and Blood Flow Support
Estrogen rises throughout pregnancy and supports uterine growth, blood flow, breast development, and placental function. It also plays a role in skin pigmentation changes, nasal congestion, and increased sensitivity to smells.
Relaxin: Flexible but Sometimes Too Flexible
Relaxin helps loosen ligaments and joints so the body can adapt to pregnancy and prepare for birth. This is useful, but it can also contribute to pelvic discomfort, back pain, and feeling less stable. Move mindfully, especially when exercising or getting out of bed.
Human Placental Lactogen: Fuel Management
Human placental lactogen helps shift how your body uses energy so more nutrients are available for the baby. It can affect insulin sensitivity, which is one reason screening for gestational diabetes usually happens between 24 and 28 weeks.
Prolactin: Preparing for Milk Production
Prolactin helps prepare the breasts for milk production. Even though full milk production usually begins after delivery, your body is already setting up the system. The construction crew is active, even if the grand opening is still months away.
Prenatal Care Around 23 Weeks Pregnant
By week 23, many people have already had the anatomy ultrasound, often performed around 18 to 22 weeks. If follow-up imaging is needed, your healthcare provider may schedule another scan to check growth, anatomy, placenta location, or amniotic fluid.
Your provider may measure your blood pressure, weight, and fundal height, which is the distance from the pubic bone to the top of the uterus. Around this stage, fundal height in centimeters often roughly corresponds to the number of weeks pregnant, though individual variation is normal.
Gestational Diabetes Screening Is Coming Soon
Gestational diabetes screening is commonly done between 24 and 28 weeks. This test checks how your body handles glucose during pregnancy. If your provider schedules it soon, do not panic. It is routine, and it helps identify blood sugar issues early so they can be managed.
Vaccines to Discuss
Ask your provider about recommended vaccines during pregnancy. Tdap is commonly given between 27 and 36 weeks to help protect your newborn from whooping cough. Flu, COVID-19, and RSV vaccine recommendations may depend on season, risk factors, and current medical guidance, so your healthcare team is the best source for your personal plan.
Healthy Tips for Week 23 of Pregnancy
Eat for Steady Energy
At 23 weeks pregnant, your body needs nutrient-dense foods to support your baby’s growth and your own health. Focus on lean protein, whole grains, fruits, vegetables, healthy fats, and calcium-rich foods. Important nutrients during pregnancy include folic acid, iron, calcium, vitamin D, iodine, choline, and omega-3 fatty acids.
If you eat fish, choose low-mercury options and follow pregnancy-safe seafood guidance. Fish such as salmon, sardines, trout, anchovies, and tilapia can provide protein and omega-3 fats. Avoid high-mercury fish and raw or undercooked seafood unless your healthcare provider gives specific advice.
Stay Hydrated
Hydration can help with headaches, constipation, swelling, and Braxton Hicks contractions. Water is ideal, but soups, fruits, smoothies, and herbal teas approved by your provider can contribute, too. If plain water tastes boring, try adding lemon, cucumber, or berries.
Move Your Body Gently
For many pregnant people, regular moderate exercise is safe and helpful. Walking, swimming, stationary cycling, and prenatal yoga are popular options. Exercise may improve mood, sleep, circulation, strength, and back comfort.
Check with your healthcare provider before starting or changing your routine, especially if you have pregnancy complications. Stop exercising and seek medical advice if you experience vaginal bleeding, dizziness, chest pain, regular painful contractions, fluid leakage, or shortness of breath before exertion.
Prioritize Sleep, Even If Sleep Is Being Rude
Sleep can become harder as your belly grows. Try sleeping on your side with a pillow between your knees and another supporting your belly. Keep screens dim before bed, eat dinner earlier if heartburn is an issue, and create a wind-down routine that signals your body it is time to rest.
Support Your Mental Health
Pregnancy can bring joy, anxiety, impatience, and emotional whiplash. Mood changes can be normal, but ongoing sadness, panic, hopelessness, or intrusive thoughts deserve support. Talk with your provider if your emotional symptoms feel heavy or interfere with daily life.
When to Call Your Healthcare Provider
Many symptoms at 23 weeks pregnant are normal, but some should be checked promptly. Contact your healthcare provider or seek urgent care if you experience:
- Vaginal bleeding
- Fluid leaking from the vagina
- Regular contractions or tightening that does not stop with rest and hydration
- Severe or persistent abdominal pain
- Severe headache, vision changes, dizziness, or fainting
- Fever of 100.4°F or higher
- Pain or burning when urinating
- Sudden swelling of the face or hands
- Chest pain or trouble breathing
- One-sided leg swelling, warmth, redness, or calf pain
- A noticeable decrease in fetal movement after you have established a regular pattern
Trust your instincts. You are not “bothering” your provider by asking about symptoms. That is literally part of the job description.
Practical Checklist for 23 Weeks Pregnant
- Confirm your next prenatal appointment.
- Ask when your gestational diabetes screening will happen.
- Review safe exercise options with your provider.
- Start thinking about childbirth education classes.
- Check whether your workplace needs any pregnancy-related paperwork.
- Choose supportive shoes and maternity clothes that do not argue with your belly.
- Begin researching pediatricians if you enjoy feeling extremely organized.
Real-Life Experiences at 23 Weeks Pregnant
Being 23 weeks pregnant can feel like standing in the middle of two worlds. You are far enough along that pregnancy feels very real, but still early enough that birth may seem distant. Many people describe this stage as the moment when strangers start noticing the bump, baby movements become part of daily life, and planning shifts from “someday” to “oh wow, we actually need diapers.”
One common experience at 23 weeks is the emotional boost of feeling the baby move more often. A flutter during a meeting, a roll after lunch, or a kick while lying in bed can make the pregnancy feel beautifully personal. It can also be funny. Some babies seem to go quiet when a partner puts a hand on the belly, then start dancing the moment the hand leaves. This is not scientifically proven mischief, but many parents would testify under oath.
Another real-life theme is body adjustment. At 23 weeks pregnant, your belly may be changing quickly. Clothes that fit last week may suddenly feel like betrayal. Waistbands become suspicious. Shoes may feel tighter by evening. You may feel proud of your changing body one minute and completely uncomfortable the next. Both feelings can coexist. Pregnancy is not a magazine cover; it is a full-body renovation with snacks.
Sleep often becomes a topic of daily negotiation. Some people begin using multiple pillows to support the belly, knees, back, and possibly their entire personality. Side sleeping may feel unfamiliar at first, especially for stomach or back sleepers. Getting comfortable can take creativity, and rolling over may require the grace of a cargo ship changing direction. A consistent bedtime routine, light stretching, and limiting late heavy meals may make nights easier.
Many pregnant people also notice stronger food preferences around this time. You might crave fruit, cereal, pickles, ice, spicy food, or a very specific sandwich from a very specific place that is unfortunately closed. Appetite may increase as nausea fades, but heartburn can complicate the menu. Smaller meals can help, especially if your stomach now seems to have the storage capacity of a coin purse.
Emotionally, 23 weeks pregnant can bring a mix of excitement and worry. You may feel thrilled when decorating the nursery or choosing names, then suddenly anxious about labor, finances, parenting, or whether you are doing everything “right.” This is common. Pregnancy invites a lot of advice, and not all of it is useful. Try to build a small circle of trusted sources: your healthcare provider, evidence-based pregnancy resources, and people who support you without turning every conversation into a cautionary tale.
Partners and family members may also become more involved around week 23 because the pregnancy is more visible and movement may be felt from the outside. This can be a sweet bonding moment. It can also be a good time to talk about practical support: appointments, household chores, meals, birth preferences, and postpartum plans. The more honest these conversations are now, the less everyone has to improvise later while sleep-deprived.
If you are working during pregnancy, week 23 may be when you begin thinking about schedules, maternity leave, workload, and physical comfort. Sitting for long stretches may make your back ache. Standing all day may increase swelling. Small adjustmentssupportive shoes, water nearby, short walking breaks, a better chair, or a footrestcan make a noticeable difference.
Most of all, the 23-week experience is not one-size-fits-all. Some people feel energetic and glowing. Others feel sore, tired, and slightly annoyed by the word “glowing.” Your pregnancy does not have to match anyone else’s timeline or mood. Pay attention to your body, keep your prenatal appointments, ask questions freely, and celebrate the small milestones. At 23 weeks pregnant, you and your baby are doing a lot of quiet, remarkable work every single day.
Conclusion
At 23 weeks pregnant, your baby is growing stronger, moving more, developing important lung structures, and becoming more responsive to sound and touch. Your body is also changing quickly, guided by powerful hormones that support pregnancy while sometimes causing heartburn, back pain, skin changes, constipation, swelling, and mood shifts.
This is a great time to stay consistent with prenatal care, prepare for upcoming gestational diabetes screening, eat nutrient-rich foods, move gently, hydrate, and listen closely to your body. Most symptoms at this stage are normal, but warning signs such as bleeding, fluid leakage, severe headache, sudden swelling, fever, chest pain, or regular contractions should be checked right away.
Week 23 is a meaningful milestone. Your baby is not just growing; your connection is growing, too. Whether you are feeling magical, uncomfortable, emotional, hungry, or all of the above before lunch, you are moving through one of pregnancy’s most remarkable chapters.
