Pregnancies that receive consistent prenatal care have measurably better outcomes for both mother and baby. The CDC reports that people who receive late or no prenatal care are more likely to experience pregnancy-related complications, including higher risks to the baby. Yet what “prenatal care” actually involves, how often you should be seen, and which tests truly matter is rarely explained in plain language.
This guide walks through the typical schedule of prenatal visits, the routine and optional screenings at each stage, when high-risk care is warranted, and what it generally costs in the US system. Every pregnancy is different, so treat this as background for the conversations you will have with your own obstetrician (OB) or midwife, who will tailor the plan to you. For pregnancy-specific complications, see our companion guides on preeclampsia, gestational hypertension, and preterm labor, all part of our broader medical conditions library.
The Standard Visit Schedule
For an uncomplicated pregnancy, the American College of Obstetricians and Gynecologists (ACOG) describes roughly 12 to 14 prenatal visits across pregnancy. The classic cadence is monthly visits through about 28 weeks, every two weeks from 28 to 36 weeks, and weekly from 36 weeks until delivery. Your own schedule may differ, and some practices are moving toward tailored schedules with fewer in-person visits for very low-risk pregnancies.
The first visit is typically the longest, and is often scheduled between 8 and 10 weeks. It includes a full medical and obstetric history, a physical exam, baseline labs, a dating ultrasound, and a discussion of genetic screening options. Subsequent routine visits are shorter (often 15 to 20 minutes), focused on weight, blood pressure, a urine check, fundal height measurement, and the fetal heartbeat. Many practices now offer some visits via telehealth or asynchronous check-ins for low-risk pregnancies.
First Trimester: Confirming and Establishing Care
Initial bloodwork at the first prenatal visit typically covers a complete blood count (CBC), blood type and Rh factor, an antibody screen, rubella and varicella immunity, hepatitis B surface antigen, HIV, and syphilis, along with a urine culture. Screening for chlamydia and gonorrhea is routine in pregnancy, and hepatitis C screening is now generally recommended in each pregnancy. A Pap smear is performed if you are due for one.
Genetic screening is usually offered in the first trimester. Options include cell-free fetal DNA (cfDNA, also called noninvasive prenatal testing or NIPT), which screens for Down syndrome (trisomy 21), trisomy 18, and trisomy 13, and which ACOG says should be offered to pregnant people of any age or risk level. Carrier screening for conditions such as cystic fibrosis, spinal muscular atrophy, and fragile X can be offered to either partner. An 11- to 13-week nuchal translucency ultrasound combines an early scan with blood markers when that approach is used. Screening tests estimate risk; they are not diagnoses.
Diagnostic testing — chorionic villus sampling (CVS) at about 10 to 13 weeks, or amniocentesis at about 15 to 20 weeks — can provide definitive answers for those with a screen-positive result or specific concerns. Both carry a small procedure-related miscarriage risk, which your clinician can put in context for your situation.
Second Trimester: Anatomy and Screening
The detailed anatomy ultrasound is generally performed between 18 and 22 weeks. It evaluates fetal organ development, measures growth, checks the placenta, and confirms or revises the due date. Major structural differences are often detected at this scan, though some appear later in pregnancy or after birth.
Maternal serum alpha-fetoprotein (MSAFP) screening, sometimes part of a quad screen, may be offered between 15 and 20 weeks if cfDNA was not used. Glucose screening for gestational diabetes typically happens between 24 and 28 weeks; a common approach is a one-hour 50-gram glucose challenge as the initial screen, with a follow-up three-hour 100-gram test if the first result is elevated. People with risk factors may be screened earlier.
Rh-negative pregnant people without antibodies are typically offered Rho(D) immune globulin (such as RhoGAM) around 28 weeks, with another dose after delivery if the baby is Rh-positive; this helps prevent problems in future pregnancies. The Tdap vaccine is recommended during every pregnancy, generally between 27 and 36 weeks, to pass whooping-cough protection to the newborn. Your provider will also discuss other recommended vaccines, such as flu and, where appropriate, RSV and COVID-19, based on the season and current guidance.
Third Trimester: Closer Monitoring
From about 28 weeks onward, blood pressure checks become more important; rising blood pressure can signal gestational hypertension or preeclampsia, which complicate a meaningful share of pregnancies. Fundal height (the distance from the pubic bone to the top of the uterus, measured in centimeters) helps track growth; a significant deviation may prompt a growth ultrasound.
Group B strep (GBS) screening is generally performed between 36 and 37 weeks via a vaginal-rectal swab. A meaningful minority of pregnant people carry GBS, and those who test positive are offered antibiotics through an IV during labor to reduce the risk of newborn infection.
Weekly visits in the final month may involve cervical exams (sometimes), fetal position checks, and discussion of labor signs. Some practices begin nonstress tests (NSTs) in the third trimester for higher-risk pregnancies, monitoring the fetal heart rate over roughly 20 minutes.
High-Risk vs Low-Risk Care
Higher-risk pregnancies often involve a maternal-fetal medicine (MFM) specialist alongside the primary obstetrician or midwife. Common reasons for MFM consultation include pre-existing diabetes or chronic hypertension, autoimmune disease, a previous preterm birth, a history of preeclampsia, twins or higher-order multiples, fetal findings on ultrasound, older maternal age (often defined as 35 or older at delivery), or significant maternal cardiac, kidney, or thyroid disease.
High-risk pregnancies typically include more frequent visits, additional ultrasounds (often for growth), and more intensive monitoring near term. Many high-risk patients deliver in hospitals with neonatal intensive care units. Lower-risk patients may deliver in standard hospitals, accredited birth centers, or, in some cases, at home with a qualified certified nurse-midwife — a decision to weigh carefully with your care team.
What Prenatal Care Costs
Total maternity care in the US commonly runs into the tens of thousands of dollars before insurance, with cesarean births generally costing more than uncomplicated vaginal births, per Peterson-KFF Health System Tracker analyses. These figures include prenatal visits, delivery, and routine postpartum care. Your out-of-pocket cost varies widely by insurance: deductibles, coinsurance, and out-of-network providers all matter, and exact amounts change year to year, so ask for an estimate.
Most ACA-compliant plans cover maternity care as an essential health benefit. Medicaid covers maternity for eligible people in every state and is the payer for a large share of US births. For those without insurance, hospital financial counselors can sometimes arrange a global maternity package or a payment plan, and Federally Qualified Health Centers offer sliding-scale prenatal care based on income.
Lifestyle and Self-Care During Pregnancy
A daily folic acid supplement of 400 to 800 micrograms, ideally started before conception, reduces the risk of neural tube defects (people with certain risk factors may be advised to take more, under clinician guidance). A standard prenatal vitamin covers folate plus iron and other essentials. The ACOG exercise guidance supports about 150 minutes of moderate-intensity activity per week for most uncomplicated pregnancies — confirm what is right for you with your provider.
Common diet recommendations include avoiding raw or undercooked meat and seafood, unpasteurized dairy and juices, deli meats unless heated, high-mercury fish (such as king mackerel, swordfish, tilefish, and shark), and large amounts of caffeine (many clinicians suggest capping intake at about 200 mg per day). Alcohol is best avoided entirely, as no amount is known to be safe in pregnancy. Stopping smoking, vaping, and cannabis reduces risks to the pregnancy.
Routine pregnancy discomforts that still deserve evaluation include severe or persistent headaches, persistent vomiting (consider hyperemesis gravidarum), decreased fetal movement after 28 weeks, any bleeding, leakage of fluid, signs of preterm labor, and significant swelling of the face or hands. When in doubt, call your provider — that is what they are there for.
When to Call Your Provider — and Warning Signs
Most pregnancies proceed without serious complications, but recognizing warning signs matters. Contact your obstetric provider promptly if you experience vaginal bleeding, severe abdominal pain, severe one-sided pain (which can indicate an ectopic pregnancy early on), persistent vomiting with an inability to keep fluids down, a fever, a severe or persistent headache, changes in your vision (such as spots, flashing, or blurring), sudden swelling of the face or hands, or decreased fetal movement after 28 weeks. Many of these can be early signs of preeclampsia or another problem that is far easier to manage when caught early.
Frequently Asked Questions
When should I schedule my first prenatal visit?
Many providers schedule the first visit between 8 and 10 weeks, but call your provider as soon as you know you are pregnant so they can advise you. Earlier visits are appropriate if you have bleeding, pain, a history of recurrent miscarriage or ectopic pregnancy, or significant medical conditions. Confirming pregnancy with a home test is a reasonable first step.
Do I need every recommended test?
Some tests are recommended for nearly everyone (blood type, infectious-disease screens, the anatomy ultrasound, glucose screening, GBS). Genetic screening is optional and personal; some people decline it. Discuss the tradeoffs with your provider rather than treating every test as mandatory or unnecessary — the right choice depends on your values and situation.
How often should I have ultrasounds?
For low-risk pregnancies, the common standard is two ultrasounds: one for dating in the first trimester and the anatomy scan at 18 to 22 weeks. Higher-risk pregnancies often require additional growth scans. Routine third-trimester ultrasounds in low-risk pregnancies have not clearly been shown to improve outcomes.
Can I get prenatal care via telehealth?
Partially, yes. Many practices use a hybrid model in which blood pressure and, with appropriate equipment, fetal heart tones can be checked at home for some routine visits, while ultrasounds, glucose screening, and key in-person exams happen at the clinic. Telehealth has expanded access in rural areas and shortened total visit time for some low-risk pregnancies.
The Bottom Line
Good prenatal care is consistent, preventive, and tailored to your specific risk profile. Knowing the standard schedule, understanding which tests are recommended at each stage, and recognizing red flags lets you engage in your own care rather than just receiving it. Most people have low-risk pregnancies and need a relatively predictable cadence of visits and screening; recognizing when something has shifted into higher-risk territory is what catches problems early. Your OB or midwife is your partner in this — bring your questions, and never hesitate to call about a symptom that worries you.
This article is general educational information, not medical advice, and does not replace care from your own obstetrician or midwife. Recommendations, schedules, and screening options are individualized and can change. Always follow your provider’s guidance for your specific pregnancy, and seek prompt or emergency care for warning signs.
