According to the CDC:

Prenatal care is an important part of a healthy pregnancy. Whether you choose a family physician, obstetrician, midwife or group prenatal care, here’s what to expect during the first few prenatal appointments.

The 1st visit

When you find out you’re pregnant, make your first prenatal appointment. Set aside time for the first visit to go over your medical history and talk about any risk factors for pregnancy problems that you may have.

Medical history

Your health care provider might ask about:

• Your menstrual cycle, gynecological history and any past pregnancies
• Your personal and family medical history
• Exposure to anything that could be toxic
• Medications you take, including prescription and over-the-counter medications, vitamins or supplements
• Your lifestyle, including your use of tobacco, alcohol, caffeine and recreational drugs
• Travel to areas where malaria, tuberculosis, Zika virus, mpox — also called monkeypox — or other infectious diseases are common

Share information about sensitive issues, such as domestic abuse or past drug use, too. This will help your health care provider take the best care of you — and your baby.

Due date

Your due date is not a prediction of when you will have your baby. It’s simply the date that you will be 40 weeks pregnant. Few people give birth on their due dates. Still, establishing your due date — or estimated date of delivery — is important. It allows your health care provider to monitor your baby’s growth and the progress of your pregnancy. Your due date also helps with scheduling tests and procedures, so they are done at the right time.

To estimate your due date, your health care provider will use the date your last period started, add seven days and count back three months. The due date will be about 40 weeks from the first day of your last period. Your health care provider can use a fetal ultrasound to help confirm the date. Typically, if the due date calculated with your last period and the due date calculated with an early ultrasound differ by more than seven days, the ultrasound is used to set the due date.

As frequency of doctor visits vary highly depending on the individual, it is highly recommend you immediately consult with your doctor with any pregnancy related questions.
