Prenatal exams

Add as favorite

As soon as you suspect that you might be pregnant, call to schedule an appointment with your gynecologist. Once your pregnancy is confirmed, you will have to take several medical exams. Don’t be anxious; taking these prenatal tests is a very normal procedure, and these tests are one of the many ways to check on your well-being and that of your growing baby. If you are a first-time mom, expect to have at least 10 antenatal visits. However, if you are a second-timer you can expect around seven.
