Prenatal Appointment Timeline
A rough guide to when you might see your OB or midwife.
During pregnancy, most people see their caregiver at least a dozen times at routine prenatal appointments — more often as the due date nears. Enter the first day of your last menstrual period (LMP) for an estimated timeline. Your own caregiver's schedule, and your individual health needs, may differ.
This timeline is general guidance, not medical advice — always follow the schedule and testing plan your own provider recommends.
The Prenatal appointment schedule below is a common starting point, not a fixed rule. Your own provider will adjust it based on how your pregnancy is going, so treat this as a general shape of what to expect rather than a checklist to hold them to.
Why Visits Get More Frequent Over Time
For a low risk pregnancy, appointments are usually about once a month through week 28, then every two weeks until week 36, then weekly until delivery. The schedule speeds up simply because there’s more to watch for as your due date gets closer, not because anything is assumed to be going wrong.
What Actually Happens At Each Visit
Most routine visits are quick: weight, blood pressure, a measurement of your belly, and a check of your baby’s heartbeat. The bigger milestones are the first trimester bloodwork and screening, the anatomy scan around 18 to 22 weeks, glucose screening for gestational diabetes around 24 to 28 weeks, and Group B strep testing near the end, usually around 36 weeks.
When Your Own Schedule Might Look Different
A first pregnancy, a high risk pregnancy, carrying multiples, or a provider’s own preferences can all shift this timeline earlier or make visits more frequent. If your schedule looks different from what’s above, that’s normal too. Your provider is tailoring it to you specifically.
