Your first prenatal appointment is the longest and most thorough visit you’ll have during pregnancy. It typically lasts 45 minutes to over an hour and covers a wide range of ground: a detailed health history, blood work, a urine sample, a physical exam, and often an ultrasound. Most providers schedule this visit between six and ten weeks of pregnancy, and you should call to book it as soon as you get a positive test.
The Health History Questionnaire
A large portion of your first visit is paperwork and conversation. Your provider needs a comprehensive picture of your health before pregnancy, so expect questions that go well beyond the basics. You’ll be asked about any previous pregnancies, including miscarriages, cesarean deliveries, and complications. You’ll also go over your surgical history, particularly any procedures involving your cervix or reproductive system.
Family medical history gets detailed attention. You’ll be asked whether anyone on your side or the baby’s father’s side has a history of conditions like Down syndrome, cystic fibrosis, sickle cell disease, heart defects, neural tube defects, or other inherited disorders. This information helps your provider determine which genetic screenings to recommend later. If you don’t know your family history well, gather what you can beforehand, but don’t stress over gaps.
Lifestyle questions are part of the intake too. Your provider will ask about alcohol, tobacco, and drug use, including cannabis and CBD products. These aren’t meant to judge you. They’re asked because even small exposures can affect fetal development, and your care team needs honest answers to keep you and your baby safe. You’ll also be asked about your mental health, relationship safety, and work environment.
Mental Health Screening
The American College of Obstetricians and Gynecologists (ACOG) recommends screening for depression and anxiety at the very first prenatal visit, not just postpartum. You’ll likely fill out a short questionnaire asking about your mood, sleep, appetite, and whether you’ve felt anxious or hopeless. The form is scored before you leave so your provider can address any concerns that same day. This screening happens again later in pregnancy and after delivery.
Blood Work and Urine Tests
Expect several vials of blood drawn at this visit. The standard prenatal panel includes a complete blood count to check for anemia, clotting issues, and signs of infection. Your blood type and Rh factor are tested because Rh-negative mothers carrying Rh-positive babies need treatment later in pregnancy to prevent complications.
You’ll also be screened for immunity to rubella (German measles), since infection during pregnancy can cause serious birth defects. Hepatitis B is routinely tested, and depending on your risk factors, hepatitis C may be added. Sexually transmitted infections like chlamydia and syphilis are checked early in pregnancy, and HIV testing is standard in most states.
A urine sample rounds out the lab work. It screens for urinary tract infections, which are common in pregnancy and can cause problems if untreated. Your urine is also checked for glucose and protein levels, which help flag early signs of gestational diabetes or preeclampsia that your provider will continue monitoring throughout pregnancy.
The Physical Exam
Your provider will take your blood pressure, weight, and other vital signs, establishing a baseline to track changes over the coming months. A breast exam and pelvic exam are common at this visit. If you’re due for a Pap smear, it’s often done now. A pelvic exam also helps your provider assess the size of your uterus, which gives a rough estimate of how far along you are.
Ultrasound and Due Date
Many providers perform a dating ultrasound at the first visit, though some schedule it separately within the first trimester. Ultrasound measurements taken before 14 weeks are the most accurate way to establish your due date, and the earlier the scan, the more precise it is. The technician or provider measures the embryo from head to rump (called a crown-rump length) and uses that to calculate gestational age.
If the ultrasound date differs from your last menstrual period by more than seven days, your due date will be adjusted to match the ultrasound. ACOG considers any pregnancy that hasn’t had an ultrasound before 22 weeks to be “suboptimally dated,” so this early scan matters for accurate timing of future tests and milestones. At six to seven weeks, you may also hear or see the heartbeat for the first time.
Genetic Screening Options
Your provider will discuss genetic screening and testing options, though most of these happen at later visits. One option increasingly offered in the first trimester is noninvasive prenatal screening (NIPT), a blood draw from the mother that analyzes fragments of the baby’s DNA to check for extra or missing chromosomes, such as those causing Down syndrome. It can be done as early as ten weeks.
If your health history or family background raises concerns, your provider may suggest genetic counseling. A counselor reviews your family history and test results to assess the chance of passing on specific conditions. Diagnostic tests like chorionic villus sampling (which takes a small sample from the placenta) can confirm results but are typically discussed only if screening suggests a higher risk.
Medication and Supplement Review
Bring a list of everything you’re currently taking: prescriptions, over-the-counter medications, vitamins, herbal supplements, and anything else. Some common medications aren’t safe during pregnancy, and your provider will go through each one to determine what to continue, stop, or swap. If you aren’t already taking a prenatal vitamin with folic acid, you’ll be told to start right away. The FDA specifically warns against using cannabis products, including CBD, during pregnancy due to possible risks to the baby.
What Happens After This Visit
For most of the past century, the standard prenatal schedule has followed the same pattern: one visit every four weeks until around 28 weeks, then every two weeks until 36 weeks, then weekly until delivery. That adds up to 12 to 14 visits total. More recently, ACOG has recommended tailoring this schedule to each patient’s risk level, meaning low-risk pregnancies may involve fewer in-person visits supplemented by phone or virtual check-ins.
Your provider will outline this schedule before you leave and let you know when to come back, usually in about four weeks. You’ll also get guidance on nutrition, exercise, warning signs to watch for, and how to reach someone between appointments. Walking out of that first visit, you should have a clear due date, a folder full of lab orders and results, and a plan for the months ahead.
