If there are two lines on the pregnancy test, the answer is soon.
Most doctors recommend arranging a first visit between 6 and 8 weeks of pregnancy, counted from the first day of your last menstrual period, not the day of the test.
Why the 6- to 8-Week Time Frame
Most ultrasounds can detect the fetal heartbeat and, hence, confirm the viability of a pregnancy at around the 6-week mark.
This initial appointment allows healthcare providers to establish a baseline for the pregnancy. Medical history is reviewed, gestational age is estimated, and potential risk factors are identified for monitoring.
The World Health Organization recommends starting first-trimester antenatal care within the first 12 weeks of pregnancy. Early visits allow commonly used screenings and assessments, including gestational dating and screening for certain genetic conditions.
What Happens at Your First Appointment
The first visit usually lasts a bit longer than follow-up appointments, as we need time to get to know you.
During this visit, your doctor may:
This visit also helps set expectations for follow-up appointments and symptoms that may need medical attention.
When You May Be Advised to Contact a Doctor Earlier
I always advise an early appointment if there are any concerning symptoms such as pain or bleeding at any point after a positive pregnancy test. Threatened miscarriage (bleeding in early pregnancy), miscarriage, or ectopic pregnancy can present with pain and bleeding, and earlier detection of these conditions can allow better treatment outcomes.
Please also request an earlier appointment if you:
Your doctor can advise whether an earlier review is appropriate or if the usual timing is suitable. In some cases, prenatal vitamins or medication adjustments may be discussed before the first visit.
Understanding the First Trimester Timeline
Pregnancy weeks begin on the first day of the last menstrual period. If a pregnancy test is positive after a missed period, healthcare providers often estimate the pregnancy at around 4 weeks.
The first trimester spans weeks 1–12. Initial appointments are commonly scheduled between weeks 6 and 8, with follow-up visits typically every four weeks if no concerns are identified.
This schedule supports monitoring during key developmental stages while avoiding unnecessary visits.
If your appointment falls slightly earlier or later than the 6- to 8-week range, this is generally acceptable. What matters most is receiving the appropriate antenatal care during the first trimester. If concerns or unusual symptoms arise, contacting a healthcare provider earlier may be appropriate.

Preparing for Your First Antenatal Visit
There are steps you can take while waiting for your appointment.
If Your Dates Are Unclear
Uncertain menstrual dates or irregular cycles are common.
During the first visit, ultrasound measurements may be used to estimate gestational age. Early measurements are frequently used to assist with pregnancy dating in the first trimester.
When booking your appointment, inform the clinic if your last period is unclear or cycles are irregular, as an earlier review may be suggested for dating purposes.
Why Early Antenatal Care Matters
Starting antenatal care in the first trimester allows healthcare providers to assess early pregnancy and plan appropriate monitoring.
Early care supports:
Regular antenatal care throughout pregnancy is associated with improved maternal and fetal health. The first appointment sets the foundation for ongoing care in the months ahead.
The commonly suggested timing for the first visit is 6 to 8 weeks after the last menstrual period. This may vary based on individual circumstances, but contacting a doctor soon after a positive pregnancy test helps ensure timely planning of antenatal care.
