Is a Transvaginal Ultrasound During Menstruation Safe or Dangerous? Here's What Doctors Explain

27 January 2026 3 min read

A transvaginal ultrasound is a medical imaging procedure used to examine the female reproductive organs, including the uterus, cervix, fallopian tubes, and ovaries. This examination is performed by inserting a slim, rod-shaped medical device called a transducer into the vagina.

But what if a transvaginal ultrasound is needed during menstruation? Is it safe and allowed? Here is the explanation.

What Is a Transvaginal Ultrasound?

A transvaginal ultrasound uses high-frequency sound waves to produce detailed images of the pelvic organs. The transducer emits sound waves that bounce off internal structures, and the returning echoes are converted into images displayed on a monitor for evaluation by medical professionals or obstetricians and gynecologists.

The procedure typically lasts between 15 to 30 minutes, depending on the purpose of the examination and the clarity of the pelvic organ structures.

Conditions That Can Be Detected with a Transvaginal Ultrasound

A doctor may recommend a transvaginal ultrasound if you experience pelvic pain, abnormal vaginal bleeding, or other reproductive health concerns. This examination can help detect various conditions, including:

Ovarian cysts
Uterine fibroids
Uterine polyps
Signs of cancer
Ectopic pregnancy or miscarriage
Causes of infertility
Position of an intrauterine device (IUD)
Location of pregnancy (inside or outside the uterus)
Gestational age
Fetal heartbeat
Early pregnancy complications

Can a Transvaginal Ultrasound Be Performed During Menstruation?

In general, a transvaginal ultrasound can be performed at any time, including during menstruation. However, during the early days of menstruation, menstrual blood may affect image clarity. For routine cases, doctors often recommend scheduling the ultrasound after menstruation ends.

However, in cases of menorrhagia (prolonged or heavy menstrual bleeding) or postmenopausal bleeding, immediate evaluation is necessary. In such situations, a transvaginal ultrasound may be recommended even during menstruation.

Tips for Undergoing a Transvaginal Ultrasound During Menstruation

Wear comfortable clothing that is easy to remove.
Follow medical instructions regarding whether your bladder should be full or empty.
Bring a book or mobile device while waiting.
Stay relaxed and follow the healthcare provider’s guidance during the procedure.

You may feel mild pressure or discomfort, but this procedure is generally painless and safe.
