Frequently Asked Medical Questions (FAQ)

Evidence-based clinical answers to common patient questions

Can I have a transvaginal ultrasound during my period?

Yes, you can safely have a transvaginal ultrasound while you are on your period. The technician uses a protective cover on the probe, so menstruation does not interfere with the procedure at all. If you wear a tampon, you will simply need to remove it right before the scan begins.

Does a transvaginal ultrasound use harmful radiation?

No, this scan does not use any radiation. It relies entirely on safe sound waves to create images of your internal organs. This makes it completely safe for women, including those who are pregnant.

Do I need to empty my bladder before the scan?

It depends on what your doctor needs to check. Sometimes an empty bladder works best because it lets the probe get closer to your organs. This other times a partially full bladder is helpful. Always follow the specific instructions given by your doctor's office.

Will I bleed after a transvaginal ultrasound?

Most women do not experience any bleeding after a transvaginal ultrasound. You might notice a small amount of light discharge from the lubricating gel used during the test, but actual bleeding is rare. Call your doctor if you experience heavy bleeding or severe pain.

Can a virgin have a transvaginal ultrasound?

Doctors generally avoid transvaginal ultrasounds for women who have not had penetrative intercourse, as it can cause significant discomfort or tear the hymen. In these cases, doctors almost always choose an abdominal ultrasound or an alternative imaging test instead.
