At 23 weeks pregnant, the baby is roughly the size of a mango and is undergoing rapid development, with organs maturing and skin thinning. The mother may experience symptoms like breathing challenges, increased hunger, and vivid dreams. It’s important to stay hydrated, attend all prenatal check-ups, and maintain a balanced diet.
Reaching the 23-week mark is a big deal. In terms of pregnancy timeline, you are now firmly in the second trimester, which many describe as the “honeymoon period” due to reduced nausea and increased energy levels (compared to the first trimester).
But more importantly, 23 weeks is often noted as the edge of viability. This means that if a baby were born this early, there is a chance—with immense medical intervention in a neonatal intensive care unit (NICU)—that they could survive outside the womb. It’s a profound medical milestone, though the goal remains a full-term pregnancy. At 23 weeks, your body and your baby are both undergoing rapid and remarkable development.
This guide blends verified KKM recommendations, symptom management tips, baby development facts, and practical steps for Malaysian mothers. You’ll also learn when to book your ultrasound and how tools like Sonobee Ultrasound and the Flabee Care App make your antenatal care easier.
How Big is Your Baby at 23 Weeks?
At 23 weeks of gestation, the fetus typically measures approximately 28–29 cm from crown to heel and weighs around 480–520 grams, just over 1 pound. These measurements are consistent with Hadlock fetal biometry charts and INTERGROWTH-21st international fetal growth standards, interpreted in line with ISUOG and ACOG ultrasound guidelines. During this stage, the baby begins accumulating more subcutaneous fat, an important process that supports temperature regulation after birth.

Despite this growth, your baby still has plenty of room to move, twist, and turn in their amniotic fluid home, which leads to those delightful kicks and jabs you’re feeling.
What to Expect at 23 Weeks Pregnant: Your Body & Symptoms
The second trimester is known for its relative comfort, but that doesn’t mean it’s symptom-free. Here’s what to expect at 23 weeks pregnant:
- A Growing Bump: Your uterus is now about 1.5 inches above your belly button, and your bump is unmistakable.
- Braxton Hicks Contractions: You might start feeling these “practice” contractions—a tightening sensation in your abdomen that comes and goes irregularly. They are normal, but if they become regular or painful, contact your healthcare provider.
- Backaches and Pelvic Pain: As your uterus expands, it shifts your center of gravity and puts strain on your back and pelvis.
- Swollen Ankles and Feet (Edema): Increased blood volume and pressure from your uterus can cause fluid retention.
- Skin Changes: You might notice a dark line (linea nigra) down your abdomen or darker patches on your face (melasma). Your stretch marks might also become more prominent.
- Increased Appetite: With morning sickness often a memory, you may find yourself feeling hungrier. Focus on nutrient-dense foods.
Why Am I So Tired at 23 Weeks Pregnant?
Feeling exhausted even after a good night’s sleep? You’re not alone. The question “why so tired at 23 weeks pregnant?” is very common. Several factors contribute to this fatigue:
- Increased Blood Volume: Your body is producing nearly 50% more blood to support your placenta and baby, which puts extra demand on your heart and energy stores.
- Sleep Disruptions: Finding a comfortable sleeping position is getting harder. You may also be waking up due to leg cramps, heartburn, or frequent trips to the bathroom.
- Physical Strain: Simply carrying extra weight and your changing posture require more energy.
- Baby’s Growth Spurt: Your body is working overtime to support your baby’s rapid development and weight gain.
Tip: Listen to your body. Rest when you can, delegate tasks, and try to take short, gentle walks to boost your energy levels.
What Position is Your Baby in at 23 Weeks?
At 23 weeks pregnant, your baby is still small enough to have a gymnastics party in your womb. So, what position is baby in at 23 weeks?
The answer is: almost any position! Your baby is still floating in ample amniotic fluid and can be head-down, breech (feet-down), or transverse (lying sideways)—and they will likely change positions multiple times a day. There is absolutely no cause for concern about their position at this stage. They still have plenty of time to get into the head-down, birth-ready position closer to your due date.
Is the Best Scan Done at 23 Weeks?
Many parents wonder, “Is the best scan done when the pregnancy reaches 23 weeks?” The answer is nuanced.
The most detailed anatomical scan, often called the anomaly scan, is typically performed between 18 and 22 weeks of pregnancy. At 23 weeks, you may have just had it or are having it very soon.
If you haven’t had it yet, a scan at 23 weeks is still perfectly timed to check your baby’s anatomy, including the brain, heart, spine, limbs, and organs. It can also check the placenta and amniotic fluid levels. So, while the ideal window is closing, a 23-week scan is still highly valuable and effective.
Second Trimester Pregnancy : Your KKM-Compliant Actionable Checklist
The second trimester is often described as a more comfortable and stable phase of pregnancy. Energy levels may improve, nausea may ease, and your baby begins rapid growth. According to the Ministry of Health Malaysia (KKM), this stage is an important time to stay proactive with antenatal care, nutrition, physical activity, and early preparation for motherhood. https://hq.moh.gov.my/bpkk/images/3.Penerbitan/2.Orang_Awam/6.Kesihatan_Ibu/PDF/3.GARIS_PANDUAN/6_garis_panduan_perkhidmatan_pra_kehamilan_di_penjagaan_kesihatan_primer_2019.pdf
Below is a KKM-aligned checklist that is relevant throughout the second trimester.
- Schedule or Complete Your Mid-Pregnancy Ultrasound
KKM recommends a detailed mid-pregnancy (anatomy) scan between 18–22 weeks. This important ultrasound assesses your baby’s growth, organ development, and overall health. If you haven’t had it yet, schedule this appointment during the second trimester. https://hq.moh.gov.my/bpkk/images/PERINATAL_CARE_MANUAL_4th_Edition_2020_11Mei2023.pdf
- Begin Planning Your Maternity Leave and Work Arrangements
Use this trimester to review your maternity leave rights under Malaysian law and discuss arrangements with your employer. Early planning reduces stress and supports mental well-being, which KKM highlights as key to prenatal health.

- Start Preparing for Baby Essentials
Create a checklist or registry of essential baby items. Gradual preparation helps avoid last-minute stress and aligns with KKM’s focus on family readiness—especially for first-time parents.
https://hq.moh.gov.my/bpkk/images/PERINATAL_CARE_MANUAL_4th_Edition_2020_11Mei2023.pdf
- Support Emotional Well-Being and Family Bonding
Activities like choosing baby names or discussing parenting plans can strengthen family bonds and emotional health. KKM and WHO both recognize emotional well-being as vital for a healthy pregnancy.
- Maintain Balanced Nutrition
Your nutritional needs increase during the second trimester. Follow KKM’s Malaysian Dietary Guidelines for Mothers to ensure adequate iron, calcium, protein, folic acid, and fibre—supporting both your health and your baby’s development.

- Practice Pelvic Floor (Kegel) Exercises
Regular pelvic floor exercises strengthen muscles that support bladder control and postpartum recovery. KKM encourages these safe, effective exercises throughout pregnancy.

- Practice Skin Care for Comfort
As your belly grows, keep skin hydrated to ease dryness and itchiness. While stretch marks are often genetic, moisturizing can improve comfort—a self-care step supported by KKM educational materials. https://www.moh.gov.my/moh/resources/Penerbitan/Perkhidmatan%20OnG%20&%20Ped/O%20&%20G/HANDBOOK_APPM__A5.pdf
- Begin Early Home or Nursery Planning
Start planning your baby’s space—whether organizing a nursery corner or preparing sleeping arrangements. Early, gradual preparation is encouraged by KKM to support emotional readiness and family involvement.
Which Exercises Are Suitable for 23 Weeks Pregnant?
Staying active is highly beneficial for both physical and mental well-being. According to KKM’s Antenatal & Postnatal Exercise Manual, regular, moderate exercise can improve fitness, reduce stress, and prepare your body for labor. https://hq.moh.gov.my/bpkk/images/3.Penerbitan/2.Orang_Awam/6.Kesihatan_Ibu/PDF/3.GARIS_PANDUAN/25_manual_senaman_antenatal_postnatal_di_klinik_kesihatan.pdf
Recommended Safe Exercises:
- Brisk Walking: A perfect low-impact cardiovascular exercise that is safe for all fitness levels.
- Swimming or Water Aerobics: The buoyancy of water supports your joints and growing belly, providing relief and a full-body workout.
- Prenatal Yoga or Pilates: Excellent for improving flexibility, core strength, and practicing breathing and relaxation techniques valuable for childbirth.
- Stationary Cycling: Provides a safe cardio workout without the risk of balance-related falls.
Key Safety Precautions:
- Avoid exercises that involve lying flat on your back for long periods after the first trimester, as this can restrict blood flow.
- Steer clear of contact sports, activities with a high risk of falling, or exercises that involve jumping or sudden directional changes.
- Always consult your doctor or a certified prenatal fitness instructor before starting any new exercise regimen.
- Listen to your body. Stop immediately and consult your healthcare provider if you experience dizziness, shortness of breath, chest pain, vaginal bleeding, or contractions.

Frequently Asked Questions (FAQ)
1. Is it normal to not feel the baby move every day at 23 weeks?
At 23 weeks, movements can still be inconsistent. Your baby is small enough to tuck into positions where you might not feel them. However, you should feel movement most days. If you are concerned about a noticeable decrease in movement, always contact your midwife or doctor.
2. How many months is 23 weeks?
23 weeks pregnant is approximately 5 months and 1 week. You are well into your fifth month.
3. Can my baby survive if born at 23 weeks?
As mentioned, 23 weeks is the cusp of viability. Survival is possible with extensive medical care, but the baby would face significant and prolonged health challenges. Every day in the womb significantly increases the chances of a healthy outcome.
4. What should I be eating at 23 weeks?
Focus on a balanced diet rich in protein (lean meat, beans, lentils), iron (leafy greens, fortified cereals), calcium (dairy, fortified plant milk), and healthy fats (avocado, nuts, olive oil).
5. Is sex safe at 23 weeks pregnant?
In a normal, low-risk pregnancy, sex is perfectly safe and can be enjoyed. Your baby is well-protected by the amniotic sac and strong uterine muscles.
6. Why do I have sharp pains in my groin?
This is likely round ligament pain—a sharp, stabbing sensation caused by the stretching of the ligaments that support your uterus. It’s normal but can be uncomfortable.
7. How much weight should I have gained by 23 weeks?
This varies for everyone, but a general guideline is between 12 and 15 pounds. Your doctor is the best person to advise you on healthy weight gain for your specific situation.
8. Can I still travel at 23 weeks?
The second trimester is often the best and safest time to travel. Always check with your airline and doctor, stay hydrated, and move around frequently on long journeys.
9. Why am I so forgetful?
“Pregnancy brain” is a real phenomenon, likely caused by hormonal changes, sleep deprivation, and the mental load of preparing for a baby.
10. When should I call the doctor?
Contact your healthcare provider immediately if you experience severe abdominal pain, vaginal bleeding, a gush of fluid, a high fever, or a sudden, complete stop in fetal movement.
