Your complete medical and surgical history should be reviewed with you by your health care team. If you have certain health conditions, it may be important to have testing (i.e., blood tests) before you become pregnant to help you have the healthiest pregnancy possible and so that the health condition remains stable during the pregnancy. If your take medications, it might be important to change the dose or type of medication before you are pregnant. If you have a family history of birth defects or inherited diseases, a genetic consultation and testing is recommended.
