After you find out you are pregnant, you should make an appointment with your doctor. Your first prenatal visit will likely be when you are 6 to 8 weeks pregnant. Your doctor will probably start by talking to you about your medical history and how you've been feeling. You'll be weighed and have your blood pressure taken. These measurements will most likely be taken during each doctor's visit.

On your first visit, you'll also have a pelvic exam to check the size and shape of your uterus (womb) and a Pap smear to check for abnormalities of the cervix (the opening of the uterus).

Urine and blood tests samples will be taken on the first visit and again at later visits. Other tests are performed, such as urine tests to check for bacteria in your urine, high sugar levels (which can be a sign of diabetes) and high protein levels (which can put you at risk for preeclampsia, a type of high blood pressure during pregnancy). Blood tests to check for low iron levels (anemia), blood cell count, infectious diseases (such as syphilis and hepatitis) and blood type are also performed.

Sometimes, an ultrasound may be done to help figure out when your baby is due or to check on your baby's growth and position in your uterus. An ultrasound uses sound waves to create an image of your baby on a video screen.

Other tests may be needed if you or your baby are at risk for any problems.
