Prenatal Visit Schedule: How Often You'll See Your OB and What Happens at Each Visit
Most people with a low-risk pregnancy see their OB/GYN or midwife about every 4 weeks until 28 weeks, every 2 weeks from 28 to 36 weeks, and every week from 36 weeks until delivery. That works out to roughly 10 to 15 visits. You'll go more often if you're carrying twins, are over 35 with other risk factors, or have a condition like high blood pressure or diabetes.
Most of those visits are short: a blood pressure check, a pee cup, the baby's heartbeat, your questions, out the door in 20 minutes. A few are long and important. Here's which is which, week by week.
The schedule at a glance
| Weeks pregnant | How often | Key tests and checks |
|---|---|---|
| About 8–12 | First visit | Health history, physical exam, first-trimester blood work, dating ultrasound |
| 10–13 | Optional screening window | Cell-free DNA (NIPT), nuchal translucency scan |
| 12–28 | Every 4 weeks | Blood pressure, weight, urine, fetal heartbeat, fundal height |
| 18–22 | One visit | Anatomy ultrasound |
| 24–28 | One visit | Glucose screening for gestational diabetes |
| 27–36 | Once | Tdap vaccine |
| 28–36 | Every 2 weeks | Blood pressure, growth checks, Rh immune globulin if Rh-negative (around 28 weeks) |
| 36–37 | One visit | Group B strep swab |
| 36 to birth | Every week | Baby's position, blood pressure, signs of labor |
Your provider may adjust this to your health, history and how the pregnancy is going.
Weeks 8 to 12: the big first visit
Block off a couple of hours. The first visit is the longest one. Expect a full medical, surgical, family and pregnancy history, a physical exam, and a batch of baseline labs: blood type and Rh factor, a complete blood count, screening for HIV, hepatitis B, hepatitis C and syphilis, rubella immunity, and a urine test. That's often several tubes of blood, so eat breakfast first.
Many practices do an early ultrasound to confirm the heartbeat and your due date. You'll also talk through genetic screening options, medications, nutrition and warning signs.
Bring: the first day of your last period, a list of every medicine and supplement, your insurance card, and any records from past pregnancies. Full walkthrough in your first prenatal appointment.
Weeks 12 to 28: the quick monthly check-ins
Most of these visits take 15 to 20 minutes. Each time, your provider usually:
- Checks your blood pressure (a rise can be an early sign of preeclampsia)
- Checks your weight
- May check your urine for protein or sugar (yes, you'll pee in a cup at almost every visit)
- Listens to the baby's heartbeat with a handheld Doppler (usually audible from around 10 to 12 weeks)
- Measures fundal height, the distance from your pubic bone to the top of your uterus, starting around 20 to 24 weeks
- Asks about symptoms, movement once you can feel it, and your questions
Two bigger appointments land here: the anatomy scan at about 18 to 22 weeks (often 30 to 60 minutes, and the one people bring a partner to) and the glucose test at about 24 to 28 weeks (a sweet drink, then a blood draw an hour later). See our guides to the 20-week anatomy scan and the pregnancy glucose test.
Weeks 28 to 36: every two weeks
Visits pick up. Your provider keeps checking blood pressure, growth and the heartbeat, and asks if the baby is moving regularly.
Also common in this window:
- Rh immune globulin around 28 weeks if your blood type is Rh-negative
- Tdap vaccine between 27 and 36 weeks, to help protect your newborn from whooping cough
- RSV vaccine between 32 and 36 weeks during RSV season, if you and your provider choose it over giving the baby an antibody shot after birth
- A repeat blood count, and sometimes repeat tests for HIV and syphilis
- Talking through birth preferences, signs of preterm labor, and what to do if your water breaks
This is a good time to settle practical things: which entrance to use for labor and delivery, how long the trip takes at rush hour, and who's driving or what car service you'll call. If you take the subway everywhere, figure out now how you'll get to the hospital at 3 a.m.
Week 36 to birth: weekly
From 36 weeks you'll usually be seen every week. Your provider will:
- Do a group B strep (GBS) swab between 36 and 37 weeks (a quick swab of the vagina and rectum; some offices let you do it yourself)
- Check the baby's position, head down or breech
- Keep a close eye on blood pressure, since preeclampsia can show up late
- Go over when to come to the hospital or birth center
If you go past your due date, expect extra monitoring like non-stress tests and ultrasounds.
When you'll be seen more often
You may have more visits, or be co-managed with a maternal-fetal medicine (MFM) specialist, if you have:
- Twins or more
- Chronic high blood pressure, diabetes, thyroid disease, kidney disease or lupus
- Gestational diabetes or preeclampsia in this pregnancy
- A history of preterm birth, stillbirth or recurrent pregnancy loss
- Concerns about the baby's growth or an abnormal ultrasound
Extra visits might mean more ultrasounds, non-stress tests or blood pressure checks. Find specialists in our maternal-fetal medicine directory.
Telehealth and home blood pressure checks
Some practices mix in telehealth for low-risk patients, especially in the second trimester. If yours does, you may be asked to check your own blood pressure at home with a validated cuff. It can save a long trip, particularly if you're commuting from Long Island or upstate. Ultrasounds, lab draws, the GBS swab and late-pregnancy checks still need to be in person.
Paying for prenatal care in New York
Don't put off care because of cost:
- NY Medicaid covers pregnant people with incomes up to 223% of the federal poverty level, and coverage continues for 12 months after the pregnancy ends.
- Presumptive eligibility lets qualified clinics and hospitals start covering your prenatal care while your Medicaid application is processed, so you don't have to wait to be seen.
- Pregnancy is a qualifying event on NY State of Health, so you can enroll in a plan once you're pregnant instead of waiting for open enrollment.
To find an OB/GYN or midwife accepting new patients, search the directory or browse providers who take Medicaid.
Questions worth asking along the way
Keep a running note on your phone between visits. Good ones:
- What's my due date, and how was it calculated?
- Which screening tests do you recommend, and which are optional?
- Which medications and supplements are safe to keep taking?
- Which symptoms should make me call right away, and what's the after-hours number?
- Which hospital or birth center do you deliver at?
- Who delivers my baby if you're not on call?
When to call your provider
Don't wait for your next appointment if you have:
- Vaginal bleeding or leaking fluid
- Severe or persistent belly pain or cramping
- A severe headache, vision changes, or sudden swelling of your face or hands
- Fever of 100.4°F (38°C) or higher
- Vomiting so severe you can't keep fluids down
- Fewer baby movements than usual in the third trimester
- Regular, painful contractions before 37 weeks
- Pain or burning when you pee
Call 911 for heavy bleeding, chest pain, trouble breathing, a seizure or fainting.
