24 Weeks Pregnant

24 Weeks Pregnant: A Key Stage for Glucose Screening and Baby Movement

At 24 weeks pregnant, the second trimester may feel more noticeable in your body and daily movement. You may feel the baby move more clearly, and gestational diabetes screening may be arranged during this stage or in the coming weeks.

The top of the uterus may be several centimeters above the belly button, and the skin on the abdomen and breasts may stretch more. Bump size and weight gain vary depending on pre-pregnancy weight, previous pregnancies, fetal position, and amniotic fluid.

How is week 24 calculated?

Pregnancy is medically dated from the first day of the last menstrual period, not from the day of fertilization. When you are described as 24 weeks pregnant, this means the calculated pregnancy age is about 24 weeks.

If your last period date is unclear or your cycles are irregular, your clinician may use previous measurements or a fetal growth ultrasound to review the estimated timing. You can use the pregnancy due date calculator as an initial estimate, then confirm it with your clinician.

Symptoms at 24 weeks pregnant

This week may affect comfort, sleep, and digestion more clearly. The following symptoms can be common, but severe or sudden symptoms should be reviewed:

• A more visible bump and a heavier feeling in the lower abdomen or pelvis.
• Itchy skin on the abdomen or breasts due to stretching and dryness.
• Dry or sensitive eyes; lubricating drops may help if your clinician or pharmacist says they are suitable.
• Heartburn or reflux, especially after large meals or lying down soon after eating.
• Constipation, gas, or bloating due to hormones and uterine pressure.
• Lower back, hip, or pelvic discomfort as balance changes.
• Mild leg cramps or fatigue after standing for long periods.
• Nasal congestion or mild gum bleeding due to increased blood flow to mucous membranes.
• Occasional mild irregular tightening, which should not be painful or regular.
• Increased clear or white vaginal discharge without a foul smell or severe itching.

Mild itching can happen as the skin stretches or becomes dry. However, very intense itching, especially on the palms or soles, or itching with yellowing of the skin, dark urine, or upper abdominal pain, needs medical assessment.

What is happening with the baby at 24 weeks?

At 24 weeks, the baby's brain continues growing quickly and movements become more coordinated. The lungs are also developing, with important structures preparing for breathing after birth.

• The brain and nervous system continue developing, helping movement and responses become more organized.
• Taste buds are developing, and the baby may swallow small amounts of amniotic fluid.
• The lungs continue developing, and cells related to surfactant production gradually mature.
• Surfactant later helps the air sacs remain open after birth, but lung maturity is not complete at this stage.
• Muscles and bones keep growing, and kicks or turns may become easier to notice.
• The kidneys continue working and producing urine within the amniotic fluid.
• Sleep-wake patterns may gradually become more noticeable.

Although week 24 is an important point in fetal development, birth at this stage is extremely premature and requires highly specialized neonatal intensive care. It should not be considered simple or safe.

How big is the baby at 24 weeks pregnant?

At 24 weeks, the baby may be more than 30 centimeters from head to heel and may weigh around 600 to 700 grams. These numbers are approximate and vary with actual pregnancy age and ultrasound measurement technique.

A single number is not enough to judge fetal health. If growth needs assessment, your clinician compares measurements with pregnancy age, previous scans, amniotic fluid, placenta position, and the full follow-up picture.

Fetal movement at 24 weeks

By 24 weeks, fetal movement may be clearer for many women. The pattern can still vary depending on fetal position, placenta location, maternal weight, and whether this is a first pregnancy. Movement may feel like fluttering, kicks, turns, or light pressure.

Movement patterns are not always as consistent at this stage as they are later in pregnancy. However, if you were clearly feeling movement and then notice a major decrease or disappearance that worries you, contact your clinician. Do not rely on drinking something cold or sweet instead of asking for advice when you are concerned.

Gestational diabetes screening between weeks 24 and 28

Around this stage, your clinician will usually discuss gestational diabetes screening, because placental hormones can increase insulin resistance. Screening may begin with a glucose challenge test GCT, or your clinician may request an oral glucose tolerance test OGTT depending on the protocol and your situation.

Gestational diabetes means high blood sugar that appears or is first recognized during pregnancy. It is not diagnosed from symptoms alone; it requires testing and clinical interpretation. Some women have no clear symptoms, which is why screening is requested even if you feel well.

• Possible symptoms can include unusual thirst, frequent urination, unusual fatigue, nausea, or sugar found in urine testing.
• Risk factors such as obesity, previous gestational diabetes, family history of diabetes, or a previous large baby may require closer follow-up.
• An elevated screening result does not always mean a final diagnosis; confirmatory testing may be needed depending on the protocol.
• If gestational diabetes is confirmed, you may need gestational diabetes follow-up with nutrition planning, glucose monitoring, and treatment if your clinician recommends it.

Ultrasound and follow-up this week

If the anatomy scan was incomplete or a finding needs review, your clinician may request a second trimester ultrasound or placenta and amniotic fluid assessment. A fetal growth ultrasound may be requested when there are risk factors, differences in uterine measurements, gestational diabetes, or multiple pregnancy.

Not every pregnancy needs an ultrasound at 24 weeks. The decision depends on earlier ultrasound findings, medical history, symptoms, abdominal growth, blood pressure, and lab results.

Tests your clinician may discuss

In addition to glucose screening, your clinician may review previous results or request tests such as a complete blood count CBC to monitor anemia, or a ferritin test if there is marked fatigue or a history of iron deficiency.

A urinalysis and urine culture may be requested if there is burning during urination, pain, fever, flank pain, or according to the follow-up protocol. Do not start medicines or supplements without a medication review during pregnancy.

Heartburn and eating at 24 weeks

Heartburn is common at this stage because of hormones and uterine pressure. Some simple steps may help before using medicines:

• Eat smaller meals rather than large meals.
• Avoid very fatty or spicy meals if they worsen your symptoms.
• Do not lie down immediately after eating, and try to leave two to three hours before bedtime.
• Slightly elevate your upper body if nighttime heartburn is troublesome.
• Ask your clinician before using heartburn medicines, especially if you have chronic conditions or take other medicines.

If you have diabetes, high blood pressure, significant weight gain, low weight, anemia, iron deficiency, or a twin pregnancy, a pregnancy nutrition consultation may help create a suitable plan.

Iron and vitamins

As pregnancy progresses and blood volume increases, iron becomes more important. However, the dose of iron during pregnancy should depend on tests and clinician assessment because high doses can cause constipation or nausea and are not suitable for everyone.

Continue pregnancy vitamins as prescribed, and do not double doses on your own. Food sources of iron include well-cooked meat, legumes, leafy greens, and fortified grains.

Sleep and safe movement

As the abdomen grows, side sleeping during pregnancy may feel more comfortable. A pillow between the knees or behind the back may reduce back and pelvic discomfort.

Gentle movement such as walking may be suitable for many pregnant women if your clinician has not restricted activity. Stop and seek advice if activity causes pain, bleeding, dizziness, severe shortness of breath, fluid leakage, or regular contractions.

When may closer follow-up be needed?

You may need high-risk pregnancy follow-up or closer appointments if there are factors that require monitoring.

• Pre-existing diabetes or gestational diabetes, high blood pressure, thyroid disease, kidney disease, heart disease, or autoimmune disease.
• Pregnancy with twins or more, or pregnancy after fertility treatment.
• Previous preterm birth, recurrent pregnancy loss, previous bleeding, or previous cesarean birth with risk factors that need review.
• An ultrasound finding that needs repeat imaging or specialist follow-up.
• Clear maternal weight concerns, anemia, or iron deficiency.
• A clear decrease in fetal movement after movement has become familiar to you.

Warning signs at 24 weeks pregnant

Seek urgent medical assessment or emergency care, depending on severity, if any of the following occur:

• Clear or increasing vaginal bleeding.
• Watery fluid leaking from the vagina or persistent unusual wetness.
• Severe or persistent abdominal or pelvic pain.
• Regular contractions, marked pelvic pressure, or severe back pain with discharge.
• Fever, chills, severe pain with urination, or flank pain.
• Very severe headache, visual changes, chest pain, severe shortness of breath, or sudden swelling.
• Persistent vomiting that prevents fluids or causes reduced urination and dizziness.
• Very intense itching, especially on the hands or feet, or itching with yellowing, dark urine, or upper abdominal pain.
• Concern about a clear decrease or disappearance of movement you had already started to feel.

Next step

After week 24, fetal movement usually becomes clearer, and you may review glucose screening results and the next visit plan with your clinician. Continue to 25 weeks pregnant, or return to the week-by-week pregnancy guide.
