Prenatal Appointment Schedule: What to Expect Week by Week
Knowing what's coming at each stage of pregnancy makes it easier to plan, ask the right questions, and feel in control of your care. Here is a breakdown of the standard prenatal visit schedule and what happens at each stage.
First Trimester (Weeks 1–13)
Your first trimester involves the most critical development for your baby — and the most testing for you. Most providers schedule 2–3 visits during this period.
- Weeks 6–10: First prenatal visit. Confirms pregnancy, estimates due date, reviews medical history. Blood work screens for blood type, Rh factor, anemia, STIs, rubella immunity, and thyroid function.
- Weeks 10–13: First trimester screening — nuchal translucency ultrasound plus PAPP-A/hCG blood test. Optional NIPT to screen for chromosomal conditions like Down syndrome.
- Weeks 11–14: CVS (Chorionic Villus Sampling) if indicated or chosen.
Second Trimester (Weeks 14–27)
Often called the "honeymoon phase" — energy often returns, and your baby's anatomy becomes visible on ultrasound.
- Week 16: Routine check, quad screen blood test option.
- Weeks 18–20: Anatomy scan (Level II ultrasound) — the major milestone scan that checks all baby's organs and often reveals baby's sex.
- Weeks 24–28: Glucose Tolerance Test (GTT) for gestational diabetes. Routine visits at weeks 24 and 28.
Third Trimester (Weeks 28–40)
Visits become more frequent — every 2 weeks from 28–36 weeks, then weekly from 36 weeks until delivery.
- Week 28: Rhogam injection if Rh-negative. Complete blood count recheck.
- Weeks 35–37: GBS (Group B Strep) swab. Review birth plan.
- Weeks 36–40: Weekly visits to check baby's position, cervical dilation, and labor readiness.
- Weeks 41–42: Post-dates monitoring with non-stress tests and induction discussion.

Frequently Asked Questions
When should I book my first prenatal appointment?
As soon as you get a positive pregnancy test, ideally by week 8. Some practices book up quickly, so call your OB-GYN or midwife right away — especially if you're over 35 or have existing health conditions.
What happens at the 20-week anatomy scan?
The anatomy scan (also called the Level II ultrasound or anomaly scan) is a detailed ultrasound that checks all of baby's major organs — brain, heart, kidneys, spine, and limbs. It also checks placenta position and amniotic fluid levels. This is often when parents find out the baby's sex if they want to know.
What is the GBS swab and why does it matter?
The Group B Streptococcus (GBS) swab is done around weeks 35–37. GBS is a common bacterium that about 25% of women carry. It's harmless to you but can occasionally cause serious infection in newborns during delivery. If you test positive, you'll receive antibiotics during labor as a precaution.
Do I really need to go to every appointment?
Yes — each visit serves a specific purpose in monitoring your health and baby's development. Missing appointments can mean missed opportunities to catch complications early. If you can't make an appointment, always call to reschedule rather than skip it entirely.
