The short explanation
Often it means ovulation is irregular rather than absent, and that is worth establishing rather than assuming. Very irregular or absent periods most commonly point to PCOS, thyroid problems, raised prolactin, or low body weight and heavy exercise — all of which are identifiable with a small set of tests and several of which are treatable.
What depends on your situation
The parts of this that change from woman to woman. Uncertainty is stated, not hidden.
- Ovulation tracking apps predict from an average cycle and are unreliable when cycles vary, which is why a blood test at the right point in your own cycle is more useful than an app's guess. Home ovulation kits can help but also mislead in PCOS.
What this answer cannot determine
The boundary of online education. These need a clinician who can see you.
- This cannot tell you whether you are ovulating or why your cycles are irregular. It also cannot interpret a test — the timing of a progesterone level relative to your own cycle is what makes it meaningful.
Questions for your clinician
Take these with you. You can add any of them to an appointment card.
- What tests would show whether I am ovulating?
- Could PCOS or my thyroid be behind this?
- Is there treatment to help me ovulate, and what does it involve?
- Should my partner be tested at the same time?
When to seek help
Clinician-approved guidance for this topic. When in doubt, being seen is never the wrong choice.
- See someone sooner if your periods have stopped entirely for three months or more, if you are producing breast milk when not feeding, or if you have severe pelvic pain.

Did this answer your question?
Whatever you choose is filed against this version of the answer, never against you, and it is never shown as a count.
“Explain more simply” asks you which part was hard to follow, so the author knows what to rewrite. “My question is different” opens a private follow-up with this answer attached.
Saving, following up and reporting are all private. Nothing you do on this page is visible to other readers or to the doctor who wrote it, unless you ask a question.
