Fetal Ultrasound

You may need a full bladder for the test. If so, you will be asked to drink water or other liquids just before the test and to avoid urinating before or during the test. Usually women in the third trimester do not need to have a full bladder.

For a transvaginal fetal ultrasound, the vaginal transducer is usually covered with a latex sleeve and a vaginal lubricant, such as K-Y Jelly. If you are allergic to latex, tell the health professional before having the test.

Talk to your doctor about any concerns you have regarding the need for the fetal ultrasound, its risks, how it will be done, or what the results will mean. To help you understand the importance of this test, fill out the medical test information form (What is a Reference PDF Opens New Window document?).
