How common are irregular periods in polycystic ovary syndrome?

PCOS is associated with changes in ovulation and hormone activity. Irregular periods may occur alongside acne, increased facial or body hair, scalp hair thinning, or difficulty becoming pregnant, but not everyone has the same combination. Irregular bleeding by itself does not diagnose PCOS. Other causes, including pregnancy, thyroid problems, medicines, and changes in weight or stress, may also need consideration.

Track bleeding dates, flow, pain, acne, hair changes, and medicines. Make an appointment if your cycles have changed, you are worried about fertility, or bleeding is difficult to manage. A clinician may review symptoms, blood tests, and sometimes an ultrasound, depending on your age and history. Treatment choices can focus on cycle control, fertility, skin or hair symptoms, and longer-term health needs.

Get urgent help for faintness, severe pelvic pain, rapidly heavy bleeding, or possible pregnancy with pain or bleeding. Seek prompt review for repeated bleeding between periods, bleeding after sex, prolonged absence of periods, or unusually heavy bleeding after a long gap. These signs should be assessed even when PCOS is already known.

What findings support or argue against PCOS? Do I need tests for other causes of irregular periods? How can we protect the womb lining if periods remain far apart? What options fit my fertility plans and other symptoms?
