When to worry about irregular periods with polycystic ovary syndrome

Polycystic ovary syndrome can affect the hormonal signals involved in ovulation. When ovulation is infrequent, periods may be widely spaced, unpredictable, or absent. Acne, increased facial or body hair, scalp hair thinning, and difficulty becoming pregnant can occur too, although not everyone has the same combination.

Irregular bleeding does not by itself confirm PCOS. Thyroid conditions, raised prolactin, pregnancy, changes in weight, medicines, and other causes can produce similar patterns. A clinician considers your history, examination, and appropriate tests.

Arrange a routine review if you go for long stretches without bleeding, your pattern changes, or you are trying to conceive. Record cycle dates, flow, pain, skin or hair changes, medicines, and any pregnancy possibility. Bring this information to your appointment.

Care may focus on predictable bleeding, acne or hair symptoms, metabolic health, or pregnancy goals. Do not rely on bleeding alone as proof that ovulation occurred. Ask how to protect the uterine lining when periods are far apart.

Get urgent help for rapidly heavy bleeding, faintness, severe weakness, severe pelvic pain, or bleeding during a possible pregnancy. Seek prompt care for sudden severe pain with vomiting, or new pain that does not settle. These symptoms need assessment regardless of a PCOS diagnosis.

Ask how often you should have a bleed, what options protect the uterine lining, which tests may clarify the diagnosis, and how treatment changes if pregnancy is planned. Ask which symptoms should lead you to seek urgent help.
