    Yes irregular periods are one of the common symptoms of PCOS but there can also be other causes. In women with PCOS irregular periods are commonly seen along with other symptoms inclulding acne and excess hair (due to high levels of male hormones) and polycystic ovaries seen on an ultrasound.  And some women with PCOS will have these other symptoms but not have irregular periods.

The recently released evidence-based guideline recommends PCOS be considered as a possible diagnosis if cycles have been irregular for two years after periods start, or after one year if the woman is considering starting the oral contraceptive pill (“the pill”).In either case an assessment should be made by a qualified professional, e.g. measuring androgen levels, to decide whether irregular periods are due to PCOS or some other cause.
