A prenatal visit is a medical checkup you receive during pregnancy to monitor your health and your baby’s development. These visits typically begin in the first trimester and continue on a regular schedule until delivery, covering everything from blood work and physical exams to ultrasounds and mental health screening. Babies born to mothers who skip prenatal care are three times more likely to have a low birth weight and five times more likely to die than those born to mothers who receive it.
How Often You’ll Go
The standard prenatal visit schedule has barely changed since it was first published in 1930. For a low-risk pregnancy, you can expect an appointment every four weeks through about the seventh month, every two weeks through the eighth month, and weekly from then until delivery. That adds up to roughly 12 to 14 visits over a full pregnancy.
Your provider can adjust this schedule based on your specific situation. If you have a chronic condition like diabetes or high blood pressure, or if you’re carrying multiples, you’ll likely go more often. High-risk pregnancies also tend to involve more ultrasounds, regular fetal monitoring, and coordination between multiple specialists such as cardiologists or endocrinologists.
What Happens at the First Visit
The first prenatal appointment is the longest and most thorough. It usually happens between weeks 8 and 12 and sets the baseline for the rest of your care. Expect it to cover three main areas: your medical history, a physical exam, and lab work.
Your provider will ask about your menstrual cycle, past pregnancies, family medical history, and any medications or supplements you take. They’ll also ask about lifestyle factors like tobacco, alcohol, caffeine, and recreational drug use, as well as any travel to areas where infections like Zika or tuberculosis are common. This is also the time to mention sensitive issues like domestic abuse or past substance use, since these can directly affect your care plan.
The physical exam typically includes measuring your weight and height to calculate your BMI and determine a healthy weight gain target. You may also get a breast exam, pelvic exam, and Pap test if you’re due for one. Depending on your health, your provider might also check your heart, lungs, and thyroid.
The blood draws at this first visit cover a lot of ground. They’ll check your blood type and Rh factor (a protein on red blood cells that can cause complications if yours doesn’t match your baby’s), measure your hemoglobin to screen for anemia, and test your immunity to rubella and chickenpox. You’ll also be screened for hepatitis B, hepatitis C, syphilis, gonorrhea, chlamydia, HIV, and tuberculosis. A urine sample checks for bladder or urinary tract infections.
What Happens at Follow-Up Visits
After that initial deep dive, routine follow-up appointments are shorter. At each one, your provider will check your blood pressure, measure your weight, and track the growth of your uterus. Starting around the midpoint of pregnancy, they’ll measure your fundal height (the distance from your pubic bone to the top of your uterus) and listen to your baby’s heartbeat. These recurring checks are designed to catch developing problems like preeclampsia, gestational diabetes, or growth restrictions before they become serious.
New tests get added at specific points. Between weeks 24 and 28, you’ll do a glucose screening to check for gestational diabetes. This involves drinking a sugary solution and having your blood drawn afterward to see how your body processes the sugar. If you had gestational diabetes in a previous pregnancy or have other risk factors, this test may happen in the first trimester instead. Later, typically around weeks 36 to 37, you’ll be screened for group B strep, a bacteria that can be harmless to you but dangerous to your baby during delivery.
Ultrasounds and Imaging
Most pregnancies include at least two ultrasounds. The first, done early in the first trimester, confirms the pregnancy, checks for a heartbeat, and estimates your due date. The second, commonly called the anatomy scan, happens around week 20 and is far more detailed.
During the anatomy scan, a sonographer takes measurements and images of your baby’s heart, brain, spine, kidneys, bladder, arms, legs, hands, feet, face, chest, lungs, stomach, and intestines. They also record the fetal heart rate, check blood flow through the umbilical cord, measure amniotic fluid levels, and examine the position of the placenta. This is often the appointment where you can learn the sex of the baby if you want to know. The whole scan typically takes 30 to 45 minutes, and if the baby isn’t in a cooperative position, you may need to come back.
Mental Health Screening
Prenatal visits aren’t just about physical health. The American College of Obstetricians and Gynecologists recommends screening for depression and anxiety at the initial prenatal visit, again later in pregnancy, and at postpartum visits. These screenings use standardized questionnaires that ask how you’ve been feeling over the past week or month, covering symptoms of depression, anxiety, mood disorders, and PTSD.
Perinatal depression and anxiety are common, affecting up to one in five pregnant people. Catching these conditions early matters because untreated mental health issues during pregnancy are linked to preterm birth, low birth weight, and difficulty bonding after delivery. If your screening scores suggest a concern, your provider can connect you with support before symptoms worsen.
High-Risk Pregnancies
If your pregnancy is classified as high risk, your visit schedule and the scope of each appointment will expand. Conditions that trigger this designation include preexisting diabetes, heart disease, autoimmune disorders, high blood pressure, or carrying twins or more. You’ll likely need extra growth ultrasounds to track your baby’s size, more frequent fetal monitoring sessions, and visits with specialists who managed your condition before pregnancy.
The goal is the same as in any pregnancy: catching problems early enough to treat them. The difference is that high-risk conditions create more opportunities for complications, so the monitoring net is tighter. Some people find the extra appointments reassuring. Others find them stressful. Either reaction is normal, and it’s worth telling your care team how you’re feeling about the process.
