A Bartholin cyst before your period

Hormonal and tissue sensitivity changes may alter how discomfort feels, yet the cyst itself forms when a Bartholin gland duct is blocked. Timing alone cannot confirm the cause of a vulval lump.

Before menstruation, some people experience fluid retention or greater sensitivity in vulval tissues. That can make pressure from an existing cyst easier to notice. A lump that repeatedly enlarges and shrinks with the cycle may have another explanation, so describe the exact location and pattern rather than assuming it is a Bartholin cyst.

A typical Bartholin cyst sits to one side near the vaginal opening. Infection can produce an abscess with stronger pain, warmth, redness and sometimes fever; these changes matter more for urgency than the point in your cycle.

Record when swelling starts, whether it changes after bleeding begins, its approximate location, and which activities hurt. Note discharge, skin changes and whether sitting, walking, sex or menstrual products add pressure. This diary can reveal a reproducible pattern for your clinician.

For mild discomfort, try a comfortably warm sitz bath, loose underwear and reduced friction. Wash the outer area gently with water and avoid squeezing, puncturing or applying fragranced products. Choose a menstrual product that does not press against the lump.

Book an examination when the lump persists after your period, recurs with successive cycles, grows, or has not previously been diagnosed. Prompt care is appropriate for pus, rapidly worsening pain, spreading redness, fever or chills because an abscess may require drainage.

Get urgent help for faintness, confusion, severe weakness or breathing difficulty. A new vulval lump after menopause also needs assessment regardless of whether it is painful or seems linked to occasional spotting.

Ask whether the lump's position is consistent with a Bartholin cyst, whether examination at a particular point in your cycle would help, and what other causes could follow a monthly pattern. If the cyst keeps returning, discuss available drainage approaches and aftercare.
