Transvaginal Ultrasound During Period: What You Need to Know

Can It Be Done?

Yes, often. But depends on indication and bleeding amount.

When It's Acceptable

• Evaluating uterus/ovaries (fibroids, cysts, PCOS, lining thickness).
• Light to moderate flow.
• Patient comfortable.

Menstrual blood can actually improve uterine/ovarian visualization (acoustic window).

When to Reschedule

• Heavy bleeding (obscures images).
• Severe cramping/pain.
• Patient preference/discomfort.
• Specific indications: endometrial biopsy timing, saline infusion sonohysterogram (best post-menses).

Tips for Comfort

• Use tampon/menstrual cup (remove before probe insertion).
• Bring pad for after.
• Communicate with sonographer; they can adjust technique.
• Take NSAID 30 min prior if cramps expected.

Decision

Discuss with your ordering provider. They know the clinical question and can advise timing.
