The short explanation
Going six months without a period with PCOS is not usually an emergency, but it is a reason to see a doctor soon. When ovulation does not happen for a long time, the womb lining is not shed regularly. Over months to years, this can cause the lining to thicken, which slightly raises the risk of problems including, rarely, cancer of the womb lining. Doctors usually aim for a bleed at least every three months in women with PCOS who are not having regular periods. There are simple ways to do this, and your doctor can also check that there is no other reason for the missed periods, such as pregnancy or thyroid problems.
What depends on your situation
The parts of this that change from woman to woman. Uncertainty is stated, not hidden.
- A pregnancy test is usually done first, even if you think it is unlikely.
- Options to protect the lining include medicine taken at intervals to bring on a bleed, the combined pill or a hormonal IUD.
- District hospitals and PHCs can do initial tests and refer you to a gynaecologist if needed.
What this answer cannot determine
The boundary of online education. These need a clinician who can see you.
- This answer cannot tell why your periods have stopped or what treatment you need. A doctor can examine you and suggest tests.
