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.

Physical exam

To find out how much weight you need to gain for a healthy pregnancy, your health care provider will measure your weight and height and calculate your body mass index.

Your health care provider might do a physical exam, including a breast exam and a pelvic exam. You might need a Pap test, depending on how long it's been since your last Pap test. Depending on your situation, you may need exams of your heart, lungs and thyroid.

Lab tests

At your first prenatal visit, blood tests might be done to:

• Check your blood type. This includes your Rh status. Rh factor is an inherited trait that refers to a protein found on the surface of red blood cells. Your pregnancy might need special care if you're Rh negative and your baby's father is Rh positive.
• Measure your hemoglobin. Hemoglobin is an iron-rich protein found in red blood cells that allows the cells to carry oxygen from your lungs to other parts of your body. Hemoglobin also carries carbon dioxide from other parts of your body to your lungs so that it can be exhaled. Low hemoglobin or a low level of red blood cells is a sign of anemia. Anemia can make you feel very tired, and it may affect your pregnancy.
• Check immunity to certain infections. This typically includes rubella and chickenpox (varicella) — unless proof of vaccination or natural immunity is documented in your medical history.
• Detect exposure to other infections. Your health care provider will suggest blood tests to detect infections such as hepatitis B, syphilis, gonorrhea, chlamydia and HIV, the virus that causes AIDS. A urine sample might also be tested for signs of a bladder or urinary tract infection.

Tests for fetal concerns

Prenatal tests can provide valuable information about your baby's health. Your health care provider will typically offer a variety of prenatal genetic screening tests. They may include ultrasound or blood tests to check for certain fetal genetic problems, such as Down syndrome.

Lifestyle issues

Your health care provider might discuss the importance of nutrition and prenatal vitamins. Ask about exercise, sex, dental care, vaccinations and travel during pregnancy, as well as other lifestyle issues. You might also talk about your work environment and the use of medications during pregnancy. If you smoke, ask your health care provider for suggestions to help you quit.

Discomforts of pregnancy

You might notice changes in your body early in your pregnancy. Your breasts might be tender and swollen. Nausea with or without vomiting (morning sickness) is also common. Talk to your health care provider if your morning sickness is severe.
