When should I have my first prenatal visit?

Around 8 weeks after your last menstrual period, or as soon as you know you're pregnant. The first visit is usually the longest — it covers your full medical history, a physical exam, initial bloodwork, and dating the pregnancy.

What happens at every prenatal visit?

The recurring checks: blood pressure, weight, urine test, baby's heartbeat, and (after about 20 weeks) fundal height measurement. Your provider also reviews symptoms and answers your questions — bring a list.

Which tests happen at which weeks of pregnancy?

Typical timing: dating ultrasound in the first trimester, anatomy scan around 18–21 weeks, glucose screening at 24–28 weeks, Tdap vaccine at 27–36 weeks (per CDC), and Group B strep screening at 35–37 weeks. Timing varies by provider — confirm yours.

How does the schedule change for a high-risk pregnancy?

More frequent visits, extra ultrasounds, and specialist monitoring. Factors that can change the schedule include being over 35, carrying multiples, diabetes, high blood pressure, or a history of preterm birth.

Is the UK schedule different from the US schedule?

Yes. Under NHS care you're offered at least 10 antenatal appointments for a first baby (around 7 if you've given birth before), with 2 ultrasound scans — rather than the US-style monthly-to-weekly cadence. Both cover the same essential checks.

Quick answer

For a typical pregnancy, prenatal visits run monthly until 28 weeks, every two weeks until 36 weeks, then weekly until birth — the standard schedule across US prenatal care guidance. Each visit checks blood pressure, urine, and fetal growth, with key tests at set weeks: anatomy scan around 20 weeks, glucose screening at 24–28 weeks, and Tdap at 27–36 weeks.

Key takeaways

The standard cadence: every 4 weeks → 28 weeks, every 2 weeks → 36 weeks, weekly → birth.
First visit is usually around 8 weeks and is the longest appointment of the pregnancy.
Every routine visit repeats the same core checks: blood pressure, weight, urine, heartbeat, fundal height.
Key tests cluster at set weeks — but timing varies by provider, so confirm your personal schedule.
The NHS schedule differs (10 appointments for a first baby, ~7 after) — same essential checks, different rhythm.

How often are prenatal appointments?

For an uncomplicated pregnancy, the standard schedule used across US prenatal care guidance is:

Weeks of pregnancy	How often	Why this rhythm
Up to 28 weeks	Every 4 weeks (monthly)	Baseline monitoring; dating and first screenings
28 to 36 weeks	Every 2 weeks	Growth tracking; complications like preeclampsia are more likely to appear
36 weeks to birth	Every week	Position, cervix, and readiness checks as labor approaches

Total: roughly 10–15 visits depending on when your first appointment happens. A 2022 ACOG–University of Michigan panel has also encouraged individualizing schedules (including some telemedicine visits for low-risk pregnancies), so your provider may adjust this — the table above is the traditional pattern, not a law.

UK readers: under NHS care, the schedule is counted differently — you're offered at least 10 antenatal appointments for a first baby and at least 7 if you've given birth before, plus 2 ultrasound scans. Same essential checks, different rhythm.

What happens at your first prenatal visit?

Usually scheduled around 8 weeks after your last menstrual period (book as soon as you know you're pregnant). It's the longest visit — expect:

Full medical history: your health, previous pregnancies, medications, family history, lifestyle.
Physical exam: blood pressure, height, weight, and often a pelvic exam and Pap smear if due.
Dating the pregnancy: last menstrual period plus possibly an early ultrasound to confirm gestational age and due date.
Initial bloodwork: blood type and Rh factor, hemoglobin, rubella immunity, hepatitis B, HIV, and others your provider orders.
Planning: prenatal vitamins review, nutrition and activity guidance, and what to expect next.

Bring: your LMP date, medication list, insurance details, and your questions — this is a great visit to use our what-to-ask-at-your-first-pregnancy-appointment list.

What happens at routine checkups in the second trimester?

Once the first visit is done, appointments settle into a quicker rhythm. The recurring checks at each visit:

Blood pressure and weight
Urine test (protein and sugar)
Baby's heartbeat (Doppler, usually audible from around 12+ weeks)
Fundal height measurement (from about 20 weeks — roughly equals weeks of gestation)
Symptom review: nausea, movement, swelling, headaches, contractions

These visits are also when most routine screenings happen (see the tests-by-week checklist below). They're short — 10 to 15 minutes is normal — so bring your questions written down.

What changes in the third trimester?

Visits get more frequent (every 2 weeks, then weekly) and more hands-on:

Growth and position: fundal height at every visit; later, checking whether the baby is head-down.
Movement counting: your provider will ask you to track daily kick counts and report any slowdown immediately.
Cervical checks: only if indicated — not routine at every visit for everyone.
Birth planning: discussing labor preferences, hospital logistics, and warning signs.
Group B strep screening and final bloodwork in the last weeks.

Which tests happen at which weeks?

Timing below is typical clinical practice — your provider's exact schedule may differ, so confirm. The one item with a firm official window: Tdap vaccine at 27–36 weeks of each pregnancy, per the CDC.

First trimester (~8–13 weeks): dating ultrasound; first-trimester screening options (discussed, not mandatory)
~18–21 weeks: anatomy scan — detailed look at baby's organs, growth, and placenta (NHS schedules the second routine scan at 18–21 weeks)
~24–28 weeks: glucose challenge screening for gestational diabetes (typical timing)
~27–36 weeks: Tdap vaccine, each pregnancy (CDC recommendation — passes protection to the baby)
~35–37 weeks: Group B streptococcus screening (typical timing)
Late third trimester: growth checks, position check, ongoing blood pressure and urine monitoring

If any screening comes back needing follow-up, your provider will explain the next step — an unclear result is common and usually just means "let's look closer."

How does the schedule change for high-risk pregnancies?

"High-risk" simply means "needs closer watching." Factors that typically increase visit frequency:

Age 35 or older
Carrying twins or more
Pre-existing conditions: diabetes, high blood pressure, thyroid disorders
Pregnancy complications: preeclampsia, gestational diabetes, growth concerns
History of preterm birth, miscarriage, or stillbirth

Changes can include: visits every 1–2 weeks from early on, additional ultrasounds, non-stress tests in the third trimester, and co-management with a maternal-fetal medicine specialist. Practically, closer watching often means growth scans every few weeks in the second half of pregnancy, home blood pressure monitoring if hypertension is a concern, and daily kick counts in the third trimester — your provider will explain what counts as normal for you. A specialist works alongside your regular provider, not instead of them. If you're told your pregnancy is high-risk, ask specifically: "What does my visit schedule look like now, and what are we watching for?" And at every visit after that: "What's the plan for the next two weeks, and what would change it?"

Questions to ask at each appointment

Three questions fit any visit. Pick from this list each time:

Is my blood pressure / weight gain / fundal height on track?
Are there any test results I should know about?
What's happening between now and the next visit — and what should I watch for?
Do I need to change anything about diet, activity, or medications?
When is my next ultrasound or screening, and do I need to prepare?
(Third trimester) What are my options if labor starts early / goes past the due date?
If I develop new symptoms — headaches, swelling, reduced movement — who do I call first, day or night?
