How will the Test Feel?
The ultrasound is not uncomfortable. A clear, water-based conducting gel is applied to the skin to help with the transmission of the sound waves. A handheld probe called a transducer is then moved over the area. In addition, your health care provider may apply pressure on your abdomen in an attempt to manually locate the position of your uterus.
The antiseptic cleansing solution will feel cold initially and may irritate your skin if it is not removed after the procedure. Some people are allergic to Betadine. Notify your health care provider if you are allergic to Betadine or if you have any other allergies.
Patients report that the actual sampling feels similar to a pap smear, where there is some discomfort and a feeling of pressure. There may be a small amount of bleeding following the procedure.
An obstetrician can perform this procedure in about 5 minutes after the preparation.
