Tracking
How do I track my cycle with PCOS?
With PCOS, log the first day of every period and any signs you notice, and expect your predicted period to be a wide window, not a precise date. PCOS can cause irregular periods, long gaps or no periods, so a range is more honest than one date. Your log also gives a doctor more to go on.
What should I log with PCOS?
- The first day of each period. This is the anchor for everything else.
- Flow. From spotting to heavy.
- Signs you’re watching. The NHS lists extra hair on the face or body, thinning hair, acne or oily skin, and weight changes.
- Mood and energy. Feeling very tired, low or anxious can come with PCOS.
- Notes. Medicines you start or stop, and anything that changes your routine.
Why are predictions less certain with PCOS?
Cycles can be irregular, long, or missing. So any estimate from past cycles will be less exact. In Seventh, you can say you have PCOS and the window widens to match. If a period is much later than your window, that is information to take to a doctor, not something an app can explain.
Can an app tell me whether I have PCOS?
No. An app can show your pattern, but only a doctor can diagnose PCOS. Doctors look for at least two of: signs of high androgens, irregular or absent periods, and polycystic ovaries on an ultrasound.
Can I get pregnant with PCOS?
PCOS can make it harder, because you might not release an egg regularly, but it doesn’t rule it out. Fertile days shown by an app are estimates, and with irregular cycles they’re even less certain. If you don’t want to get pregnant, use contraception.
When should I see a doctor?
See a doctor if you think you might have PCOS, or your symptoms are affecting everyday life, work or relationships. PCOS can raise the risk of type 2 diabetes, high blood pressure and heart disease later, so it’s worth talking about even if you feel fine.
Frequently asked questions
How long should I track before seeing a doctor?
You don’t need to wait. The NHS says to see a GP if your periods are irregular. A few months of dates makes the visit more useful.
Is it PCOS or PMOS?
Both names refer to the same condition. In 2026 it began to be renamed PMOS (polyendocrine metabolic ovarian syndrome), so you will see both.
Will my period ever be regular?
It can improve with treatment. The NHS says the combined pill may help make periods more regular, and other treatments depend on the cause.
