What Happens at a Third-Trimester Checkup?

Care As Your Due Date Approaches

As your due date approaches, prenatal visits help your care team check on your health and your baby’s growth, review new symptoms, and prepare for labor and the weeks after birth. You can bring up concerns even if they seem like ordinary late-pregnancy discomforts. The Mayo Clinic’s guide to third-trimester visits describes common check-in topics, including contractions, fluid leakage, bleeding, blood pressure, and fetal movement.

There is no single schedule or checklist that fits every pregnancy. Visit timing and monitoring may depend on your health, pregnancy history, emerging concerns, and preferences. ACOG guidance on tailored prenatal care supports making care plans around individual needs through shared decision-making. At Raveco, obstetric care is personalized, so you can discuss what monitoring is appropriate and how the plan can support your circumstances as birth nears.

What Happens During a Checkup

A third-trimester prenatal appointment usually combines a brief health check with time to discuss how you are feeling. Your clinician may check your blood pressure and weight, listen to your baby’s heartbeat, ask about fetal movement, and measure your abdomen to assess growth. Fundal height, the distance from the pubic bone to the top of the uterus, is one way to follow growth during in-person visits. These assessments are adjusted to your pregnancy and health history, rather than being identical for everyone.

Your care team may ask about contractions, pain, fluid leakage, bleeding, swelling, mood, sleep, and other changes. They may also review earlier test results and follow up on concerns from a previous visit. Tell your clinician about symptoms that are troubling you, even if they seem like ordinary late-pregnancy discomforts. At Raveco in Queens, care is centered on personalized obstetrics and gynecology, so your questions and circumstances can inform your care.

How Visit Schedules May Change

In an uncomplicated pregnancy, appointments often become more frequent as delivery approaches. A common pattern is visits about every two weeks from 28 to 36 weeks, followed by weekly visits until birth, though the timing varies by practice and individual needs. MedlinePlus’ third-trimester guidance describes this general schedule, while noting that extra monitoring may be recommended for some pregnancies.

How often are prenatal visits scheduled during the third trimester? Your clinician may adjust the plan based on your health, pregnancy history, test results, and any new concerns. The American College of Obstetricians and Gynecologists’ guidance on tailored prenatal care supports adapting visit frequency and content to individual needs.

Tests and Screenings With a Purpose

What tests or screenings may be done during the third trimester?

There is no single test list for every pregnancy. Your clinician may recommend screening based on your health, pregnancy history, earlier results, and any new concerns. At Raveco, a Queens obstetrics provider can tailor discussions about testing to your individual care needs, rather than assuming every patient needs the same checks.

A common late-pregnancy test is screening for group B streptococcus (GBS), usually with swabs from the vagina and rectum around weeks 36 to 37. GBS often causes no symptoms in the pregnant person, but can make a newborn seriously ill. If the result is positive, antibiotics are given during labor to help reduce the chance of passing the bacteria to the baby. Read more about GBS screening and prenatal testing, and see Mayo Clinic’s guidance on GBS testing.

Other tests depend on your circumstances. A blood test may check for anemia, especially if it was found earlier in pregnancy. Repeat screening for HIV or syphilis may be appropriate when personal risk or clinical guidance indicates it. If you are Rh-negative, your clinician may discuss Rh immune globulin to help prevent your body from forming antibodies that could harm the baby. Ask what a proposed test checks for and when to expect its results.

Blood pressure is commonly checked during prenatal visits because high blood pressure can signal preeclampsia. Urine testing for protein is not necessarily done at every visit; your clinician may order it when blood pressure or other findings raise concern. For gestational diabetes, care may include ongoing blood-glucose monitoring and conversations about food and activity. An ultrasound or fetal monitoring may also be recommended if there is a specific medical reason. ACOG guidance on prenatal care supports care tailored to an individual’s needs, so ask why each test is recommended and how it may affect your care plan.

When an Ultrasound May Be Offered

A third-trimester ultrasound, including one at 32 weeks, is not routine for every uncomplicated pregnancy. Evidence for universal growth scans in pregnancies without growth concerns is limited, so imaging is usually guided by individual needs and findings from other parts of prenatal care. ACOG’s guidance on tailored prenatal care supports adjusting monitoring to each patient’s circumstances.

A clinician may recommend a scan when measurements raise concern about the baby’s growth or when amniotic fluid needs assessment. Ultrasound may also help check fetal position, evaluate well-being in a high-risk pregnancy, or see whether placenta previa has resolved. The reason for imaging should be specific to your pregnancy, rather than simply the week of gestation.

If the baby is breech, your clinician may discuss options intended to turn the baby head-down. If placenta previa persists, it can affect delivery planning, including whether a cesarean birth may be recommended. A scan can therefore provide information that helps guide decisions, though what happens next depends on the findings and your overall situation.

At Raveco, pregnancy care is provided through a Queens-based OB-GYN practice focused on personalized care. If an ultrasound is proposed, ask what it is meant to assess, what the possible results could mean, and whether they might change your care plan. For an overview of how prenatal testing decisions can be discussed, see prenatal screening explained.

Symptoms Worth Reporting Promptly

What symptoms should prompt a call to my clinician during the third trimester? Contact your maternity care team promptly about vaginal bleeding, fluid leaking or a gush of fluid, regular painful contractions, or a noticeable decrease in your baby’s usual movement. Also report a severe or persistent headache, vision changes, severe abdominal pain, sudden swelling of your face or hands, fever, or difficulty breathing. MedlinePlus lists these and other symptoms that warrant a call.

A change in movement matters even if you are not sure how to count kicks. Ask your clinician which movement-tracking approach to use and what to do if activity seems reduced. Mayo Clinic’s third-trimester guidance also advises telling your care team when the baby moves less than usual.

Preeclampsia can develop without obvious symptoms, so blood-pressure checks during prenatal care are important. A sudden rise in pressure may alert your clinician to a problem; severe cases can require hospital care. Do not wait for swelling or a headache before raising a concern.

If you are uncertain whether a symptom needs attention, call and follow the instructions your care team has provided. Raveco provides personalized obstetric and gynecologic care in Queens, where discussing how to reach the team can be part of your pregnancy care. Seek emergency care for severe symptoms, heavy bleeding, chest pain, fainting, or seizures, or if you cannot reach your maternity team.

Raveco’s comprehensive obstetric care can also support conversations about symptoms that feel unusual or are changing. Trust your concern, describe what you are experiencing, and ask what to do next.

Questions to Bring to Your Visit

What questions should I ask at a third-trimester prenatal visit?

Bring a short list so you can use your appointment time well. Ask what to expect before your next visit, how your schedule may change, and what any recent test results mean. You can also ask whether you need a screening or vaccination, and what care would involve if you test positive for group B strep. The Mayo Clinic’s third-trimester visit guide suggests discussing fetal movement and when to contact your care team.

Be specific about when to call or seek urgent evaluation for reduced movement, bleeding, fluid leakage, or contractions. Ask how to recognize labor, where to go, and how to reach your team after hours. You might also discuss pain-management options and which birth preferences can be accommodated if circumstances change.

Use the visit to raise practical questions about feeding, newborn care, and choosing a pediatrician. If your practice shares on-call coverage, ask whether you may meet other clinicians who could attend the birth. Raveco provides personalized obstetric care in Queens, and its prenatal care guidance includes discussion of birth plans, feeding intentions, and postpartum care.

Your clinician can tailor answers to your health history and preferences. ACOG also emphasizes shared decision-making when developing and updating a prenatal care plan (ACOG guidance on tailored prenatal care).

Understanding Pregnancy Timing

Pregnancy references do not all use the same boundary for the third trimester. Some place its start at 27 weeks and others at 28 weeks, so ask your clinician which convention they use when discussing your appointments. You can also review how gestational timing is defined.

The labels for the final weeks distinguish early term from full term: 37 weeks is early term, not full term. Full term begins at 39 weeks, 0 days and continues through 40 weeks, 6 days. A pregnancy at 41 weeks is late term, and at 42 weeks or later it is postterm.

These categories help frame conversations about monitoring, birth planning, and recommendations if pregnancy continues beyond the estimated due date. They do not mean every patient will follow the same visit schedule or need the same care. Your clinician can explain how gestational age, visit timing, and care needs apply to your specific pregnancy.

A Plan That Fits Your Pregnancy

Late-pregnancy checkups combine routine monitoring with care shaped by your health, pregnancy history, and current concerns. The right visit schedule and tests can differ from person to person, as outlined in ACOG’s guidance on tailored prenatal care.

At Raveco, personalized obstetrics and gynecology care in Queens gives patients space to discuss their needs and preferences with their care team. Ask which checks and follow-up are appropriate for you, and contact your maternity team between visits if a symptom or change concerns you.
