If you recently took a pregnancy test and saw that the results were positive, you may want to have an ultrasound. An ultrasound procedure can tell you some important information about your pregnancy. It can also help you in the decision-making process of your pregnancy. An ultrasound will tell you how far along you are in your pregnancy, whether there is a fetal heartbeat present and where the pregnancy is developing. All of this information is crucial to know to help determine the viability of your pregnancy.
