Your Prenatal Visit Schedule, by Trimester
SaveA standard prenatal schedule is about every 4 weeks until 28 weeks, every 2 weeks until 36 weeks, then weekly until birth, roughly 12 to 14 visits in an uncomplicated first pregnancy. Visits grow more frequent late in pregnancy because problems such as preeclampsia tend to surface then. Higher-risk pregnancies may need more.

How often are prenatal appointments?
A standard prenatal schedule front-loads convenience and back-loads attention. According to the Office on Women's Health, most people see their clinician about every 4 weeks through 28 weeks, every 2 weeks from 28 to 36 weeks, and weekly after 36 weeks 1Ref 1Office on Women's Health (U.S. HHS) (2025).Prenatal care.The common United States prenatal visit cadence of roughly every four weeks to 28 weeks, every two weeks to 36 weeks, then weekly, and the tests done as part of routine prenatal care. That adds up to roughly 12 to 14 visits across an uncomplicated pregnancy. Guidance in other health systems differs, since NICE recommends about 10 appointments for a first pregnancy and 7 for later ones, using fewer routine visits 2Ref 2National Institute for Health and Care Excellence (2024).Antenatal care (NG201).A reduced-visit antenatal schedule of about ten appointments for a first pregnancy and seven for subsequent pregnancies, individualized to need. If you are newly expecting, our guide on how to book a first prenatal visit covers when to start. The exact number flexes with your health and how the pregnancy progresses.
What happens in the first trimester?
First-trimester visits focus on confirming the pregnancy and building a baseline. The first appointment, usually between 8 and 12 weeks, tends to be the longest, covering medical history, a physical exam, blood work, a urine test, and often a dating ultrasound to estimate the due date. Blood tests check blood type, immunity, and screening for certain infections. Clinicians also review safe medications and prenatal vitamins, and they may discuss genetic screening options. Early visits are also when nausea and other symptoms get addressed. In a first pregnancy, this baseline visit often runs longer because there is more history to gather.
What changes in the second trimester?
Second-trimester visits are typically shorter and follow a steady rhythm. Each one checks weight, blood pressure, urine, the height of the uterus, and the baby's heartbeat. An anatomy ultrasound around 18 to 22 weeks looks at the baby's development in detail. Between 24 and 28 weeks, ACOG recommends screening for gestational diabetes with a glucose test 3Ref 3American College of Obstetricians and Gynecologists (2018).ACOG Practice Bulletin No. 190: Gestational Diabetes Mellitus.Screening for gestational diabetes with a glucose test at 24 to 28 weeks of pregnancy. If earlier bloodwork showed low iron or another issue, this is often when it is rechecked. Many people also feel first movements during this stretch. The visits can feel routine by design, since the goal is to catch small changes in blood pressure or growth before they become problems.
Why do visits get more frequent near the end?
Late-pregnancy visits get closer together because risk rises with time. From about 36 weeks, weekly visits let clinicians watch blood pressure, fetal growth, and position as the due date approaches. Around 36 to 37 weeks, ACOG recommends a group B strep swab to guide antibiotics during labor if needed 4Ref 4American College of Obstetricians and Gynecologists (2020).Prevention of Group B Streptococcal Early-Onset Disease in Newborns: ACOG Committee Opinion, Number 797.Group B streptococcus screening by vaginal-rectal swab at 36 to 37 weeks to guide intrapartum antibiotics. Later checks may include cervical exams, vaccines such as Tdap, and planning for delivery. Conditions such as preeclampsia most often appear in the third trimester, which is precisely why monitoring intensifies then. According to NICE, the schedule can still be individualized, so someone with a straightforward pregnancy may have fewer late visits than someone being watched closely 2Ref 2National Institute for Health and Care Excellence (2024).Antenatal care (NG201).A reduced-visit antenatal schedule of about ten appointments for a first pregnancy and seven for subsequent pregnancies, individualized to need.
When to contact your prenatal team
Certain symptoms are reasons to contact your prenatal team between scheduled visits, no matter where you are in the calendar. Heavy bleeding, severe or constant abdominal pain, a bad headache with vision changes, sudden swelling, a noticeable drop in the baby's movements later in pregnancy, or leaking fluid all warrant a prompt call. Missing or spacing out visits also matters, since much of prenatal care is about catching quiet changes early. If scheduling is hard, our guide to booking a prenatal appointment can help. Keeping a running list of questions between visits means small concerns get answered before they grow. Gale can help you keep track of which tests happen at which weeks so nothing slips.

Reasons to call your prenatal team between visits
- —Heavy vaginal bleeding or a gush of fluid is a reason to seek urgent evaluation
- —A severe headache with vision changes or sudden swelling may signal preeclampsia and is a reason to seek same-day review
- —A noticeable drop in the baby's movements in the third trimester is a reason to contact your prenatal team right away
- —Severe or constant abdominal pain is a reason to seek prompt clinician review
- —Regular contractions or cramping before 37 weeks is a reason to seek same-day evaluation
If you have heavy bleeding, a severe headache with vision changes, a marked drop in the baby's movements, or regular contractions before 37 weeks, seek urgent evaluation right away through your prenatal team, labor and delivery unit, or the nearest emergency room.
