What does missed period feel like with polycystic ovary syndrome?

You may notice that expected bleeding does not start, or that your cycles become widely spaced and difficult to predict. Some people have pelvic heaviness, bloating, acne, increased facial or body hair, or scalp hair thinning, while others feel no change at all. Polycystic ovary syndrome can interfere with regular ovulation, so the uterine lining may not follow a predictable monthly pattern. A missed period can also have other explanations, including pregnancy, stress, changes in weight, intense exercise, thyroid problems, or some medicines.

Record the first day of each bleed, days without bleeding, pain, discharge, medicines, and any home pregnancy test result. If pregnancy is possible, take a test according to its instructions. Arrange a clinician visit if missed periods recur or your cycles have changed, because assessment may include a pregnancy check, medical history, examination, and blood tests. Do not start hormone treatment or supplements without guidance.

Seek urgent care for severe or one-sided pelvic pain, fainting, marked weakness, or heavy bleeding, especially if pregnancy is possible. Contact a clinician promptly for new vision changes, severe headache, or unusual breast discharge. These symptoms need assessment because they may point to causes beyond an irregular cycle.

Ask whether your pattern fits polycystic ovary syndrome, whether pregnancy or another hormone condition should be checked, and how to protect the uterine lining when periods are infrequent. You can also ask which symptoms should trigger an earlier review and how to track ovulation if you are planning pregnancy.
