Prenatal Care Schedule

Key takeaways

• First visit: as soon as you think you are pregnant, ideally in the first trimester
• Typical visits up to 28 weeks: about every 4 weeks
• Most useful single change: Call to book your first visit as soon as you have a positive pregnancy test.
• Commonest mistake: Waiting until you "feel pregnant" or until the second trimester to book a first visit.
• See a doctor if any of the signs under "When to get help" below apply to you.

Why it matters

Regular visits let your care team track your blood pressure, your weight and the baby's growth, and catch problems such as gestational diabetes or preeclampsia early, when they are easier to manage.

What helps

• Call to book your first visit as soon as you have a positive pregnancy test
• Bring a list of every medicine and supplement you take, including over-the-counter products
• Write questions down between visits so they do not get forgotten in the appointment
• Ask your team which schedule fits you; people with health conditions or higher-risk pregnancies are often seen more often
• If cost or insurance is a barrier, ask about Medicaid, which covers prenatal care in every state for those who qualify

What to avoid

• Waiting until you "feel pregnant" or until the second trimester to book a first visit
• Skipping visits because you feel well, since high blood pressure and high blood sugar often cause no symptoms
• Stopping a prescribed medicine on your own when you find out you are pregnant; ask first

In depth

Prenatal care is built around a simple idea: many of the problems that matter most in pregnancy develop quietly and can be spotted with routine checks long before they cause symptoms. Blood pressure, urine, weight, the size of the uterus and the baby's heartbeat are measured over and over, and it is the trend across visits, not any single reading, that tells your team whether things are on track.

The schedule gets more frequent as pregnancy goes on because the risks change. Early visits focus on confirming the due date, reviewing your health history and running baseline blood tests. Later visits focus on conditions that tend to appear in the second half of pregnancy, such as preeclampsia and gestational diabetes, and on the baby's growth and position as birth approaches.

Your care can be led by an obstetrician-gynecologist, a family physician or a certified nurse-midwife, and some people with complex health conditions are also seen by a maternal-fetal medicine specialist. Whoever leads your care, the aim is the same: a relationship where you feel able to raise worries early, and a plan for birth and the weeks afterward that fits your health and your preferences.

Signs and symptoms

• Missing a period or a positive home pregnancy test, the usual cue to book the first visit
• Nausea, breast tenderness and tiredness in the first trimester, which are worth mentioning even when mild
• Feeling the baby move for the first time, usually somewhere in the middle of pregnancy
• Tightening of the belly that comes and goes, which your team can help you tell apart from labor
• New swelling, headaches or vision changes later in pregnancy, which should never wait for the next scheduled visit

Causes and risk factors

• Chronic conditions such as high blood pressure, diabetes, thyroid disease or epilepsy, which usually mean more frequent visits
• Being pregnant with twins or more
• A previous preterm birth, preeclampsia, stillbirth or cesarean birth
• Age at either end of the reproductive range
• Lack of insurance, transportation or time off work, which are common reasons visits get missed
• Starting care late, which shortens the window for early screening tests

How it is checked

The first visit is usually the longest. Expect questions about your periods, past pregnancies, medical and family history, medicines and lifestyle, a physical exam and blood tests that commonly include blood type, a blood count, and screening for infections such as HIV, hepatitis B and syphilis. An ultrasound may be used to confirm the due date, especially if your last period is uncertain.

Later visits are shorter but follow a routine: blood pressure, weight, a urine check, measuring the height of the uterus and listening to the baby's heartbeat. Specific screening tests are timed to particular weeks, including optional genetic screening early on, an anatomy ultrasound in the second trimester, the glucose test for gestational diabetes and the group B strep test near the end.

When to get help

Call your prenatal care provider promptly for a headache that will not go away, vision changes, fever of 100.4°F (38°C) or higher, severe swelling of the face or hands, vaginal bleeding or leaking fluid, or a baby that is moving less than usual. Call 911 for chest pain, trouble breathing, a seizure, fainting, or thoughts of harming yourself or your baby.
