The sixth month commonly refers to around weeks 21–24; month boundaries vary. Use your recorded gestational age in weeks and days when planning care. This is a period when fetal movement often becomes more noticeable and the pregnancy moves toward the later second trimester. Learn about baby development, tests, nutrition, activity and important warning signs.
The sixth month is commonly described as weeks 21–24. The fetus continues rapid growth, becomes more active, develops hearing and continues maturing the lungs and nervous system. Many people feel regular movements during this period, although timing varies. Antenatal care continues, and gestational diabetes testing may be scheduled around 24–28 weeks depending on risk factors and the local care protocol.
Weeks 21–24 are part of the second trimester. The fetus continues growing and developing essential skills, while your changing body may affect posture, sleep, digestion and comfort. Pregnancy experiences differ, so your obstetrician's assessment remains more important than a week-by-week checklist alone.
The baby continues developing hearing, movement, swallowing and breathing-related skills. The nervous system and other organs continue to mature.
Movements may feel like kicks, rolls, swishes or jerks. There is no universal number of movements that is normal for every baby; learning your baby's usual pattern becomes important.
As the uterus grows, some symptoms become more noticeable. Not everyone experiences all of these symptoms.
Changes in posture, abdominal growth and pregnancy-related ligament changes can contribute to back discomfort.
Hormonal and physical changes can contribute to reflux or indigestion. Smaller meals and remaining upright after eating may help.
Leg cramps can occur during pregnancy. Discuss frequent or severe cramps with your clinician.
A growing abdomen, fetal movement and changing body position can make sleep and daily comfort more challenging.
Testing is individualized according to your pregnancy history, screening results, symptoms and local antenatal protocol.
| Test / Assessment | Typical timing or role | Why it may be discussed |
|---|---|---|
| 20-week / anatomy ultrasound | Usually around 18–21 or 22 weeks | Detailed assessment of fetal anatomy and development, with evaluation of the placenta and other visible structures. |
| Gestational diabetes screening | Commonly 24–28 weeks; confirm your care plan | Checks for diabetes that develops during pregnancy; earlier testing may be considered for people at higher risk. |
| Routine antenatal assessment | According to your care schedule | May include blood pressure, urine testing, symptom review, weight and other assessments. |
| Additional ultrasound or monitoring | Only when clinically indicated | May be recommended for growth concerns, multiple pregnancy, bleeding, placental concerns or other risk factors. |
Ask which glucose test is being ordered and whether fasting is required. Instructions differ between tests; do not assume that all pregnancy glucose tests use the same preparation.
Gestational diabetes screening is commonly scheduled between 24 and 28 weeks. Ask your pregnancy-care team when your test is due, even if you feel well. Some people are tested earlier because of risk factors or previous pregnancy history. The exact test and preparation vary by healthcare system and clinical protocol.
If gestational diabetes is diagnosed, treatment may include nutrition changes, physical activity, glucose monitoring and medication when needed. Follow the plan provided by your pregnancy-care team.
The NHS advises that most people begin to feel their baby's movements between 16 and 24 weeks. Movements can feel like fluttering, bubbling, rolling, swishing or kicks. If this is a first pregnancy, movement may not be noticed until after 20 weeks.
Continue a balanced pregnancy diet that provides protein, fiber, iron, calcium and other nutrients required during pregnancy.
For many people with uncomplicated pregnancies, appropriate moderate activity can continue. Walking is one practical option, while other activities should match your health, fitness level and obstetrician's advice.
Regular tightenings, period-like pain, unusual backache or a gush or trickle of fluid before 37 weeks need immediate maternity advice. Assessment is needed even if you are unsure whether these are contractions.
Contact your obstetrician or seek urgent medical assessment for symptoms that are severe, sudden, worsening or unusual for you.
My Health Hospitals provides obstetric and gynecology services at its Kukatpally and Tarnaka branches. Antenatal care should be individualized according to gestational age, medical history, screening results and pregnancy risk factors.
The sixth month commonly refers to around weeks 21 to 24, but month boundaries vary. Plan care using your recorded gestational age in weeks and days.
The fetus continues growing rapidly, developing stronger movements, hearing sounds from outside the womb and maturing the lungs, nervous system and other body systems.
Common symptoms can include a growing abdomen, backache, pelvic or round-ligament discomfort, heartburn, constipation, leg cramps, skin changes, sleep difficulty and increased awareness of fetal movement.
First movements are commonly noticed between 16 and 24 weeks, sometimes after 20 weeks in a first pregnancy. If none have been felt by 24 weeks, contact your maternity team. Once movements are familiar, a reduction or change needs immediate advice.
The mid-pregnancy anatomy scan is an ultrasound usually performed around 18 to 21 or 22 weeks depending on local practice. It evaluates fetal anatomy and development and may also assess the placenta and other pregnancy structures.
Your clinician may review the anatomy scan, routine antenatal checks and screening results. Depending on your risk factors and local schedule, gestational diabetes testing may be planned for 24 to 28 weeks.
Testing is commonly scheduled at 24 to 28 weeks; earlier testing may also be advised. Confirm your own test date and the laboratory preparation instructions with your pregnancy-care team.
Continue supplements recommended by your obstetrician. Iron, folic acid, calcium, vitamin D or other supplements may be advised based on your diet, laboratory results and pregnancy needs.
Aim for a balanced diet containing protein, vegetables, fruits, whole grains, calcium-rich foods, iron-rich foods and adequate fluids. Food choices should also follow pregnancy food-safety guidance.
Avoid alcohol and tobacco, raw or undercooked animal foods and unpasteurized products. Follow safe food preparation and storage practices and ask your clinician about caffeine, supplements and herbal products.
For many uncomplicated pregnancies, walking and other suitable moderate activity are appropriate. Exercise should be individualized if your obstetrician has advised restrictions.
Backache is common as the abdomen grows and posture and ligaments change. Severe pain, pain with fever or urinary symptoms, bleeding, fluid leakage or other concerning symptoms requires medical assessment.
Mild intermittent discomfort can occur from ligament stretching, constipation or other pregnancy changes. Severe, persistent or worsening pain should be assessed promptly.
There is no single normal daily count. Learn your baby's usual pattern. If movements reduce, stop or change, contact your maternity team immediately, including at night. Do not wait until the next day or rely on a home Doppler.
Comfort varies. As pregnancy advances, many people find side sleeping more comfortable. Discuss sleep positioning with your clinician, particularly if you have medical or pregnancy complications.
If you have never felt fetal movement by 24 weeks, contact your maternity or obstetric care team so the baby's heartbeat and wellbeing can be assessed.
Seek prompt medical care for vaginal bleeding, fluid leakage, severe or persistent abdominal pain, regular painful contractions, severe headache or vision changes, fever, fainting, or reduced or changed fetal movement.
Attend antenatal visits, complete recommended screening, follow your nutrition and supplement plan, stay appropriately active, monitor your baby's usual movement pattern and contact your maternity team when warning signs occur.
If you are 21–24 weeks pregnant and have questions about fetal movement, tests, nutrition, gestational diabetes screening or pregnancy symptoms, discuss them with your obstetrician at My Health Hospitals.
