Heavy bleeding is measurable — and worth measuring.
Any bleeding after menopause (12+ months with no period), bleeding after sex, or spotting with severe pain or fever should be checked by a clinician promptly.
Common reasons for spotting between periods
Ovulation
A little spotting mid-cycle, around the time you ovulate, is common and usually harmless. Tracking when it happens against your cycle helps you recognise it for what it is.
Hormonal contraception
Breakthrough bleeding is common in the first few months of starting or switching the pill, implant, injection or IUD, and after a missed pill. It usually settles; mention it if it doesn't.
Early pregnancy
Light spotting can happen in early pregnancy, including around the time a period would be due. If there's any chance you're pregnant, take a test — and seek advice for spotting with pain.
Perimenopause
As cycles become less regular in the run-up to menopause, spotting between periods is common. Bleeding after a full year with no period, though, always needs checking.
Infections or growths
Some infections (including STIs), polyps or fibroids can cause spotting, sometimes after sex. These are treatable, which is exactly why persistent spotting is worth a clinician's look rather than waiting it out.
Missed pills, stress or thyroid changes
Disruptions to your routine or hormones — a stressful stretch, big travel, thyroid shifts — can nudge extra bleeding. A pattern over several cycles is more meaningful than a one-off.
Common questions
- Is spotting between periods normal?
- Occasional light spotting — especially around ovulation or in the first months on a new contraceptive — is common and usually harmless. Regular, heavy, or persistent spotting is worth getting checked.
- What colour is spotting usually?
- Anywhere from pink to red to brown. Brown usually just means older blood. Colour alone doesn't tell you the cause — the timing, amount and any other symptoms matter more, which is why tracking helps.
- When should I see a doctor about spotting?
- See a clinician for spotting that's persistent or heavy, bleeding after sex, spotting with pain, fever or unusual discharge, any bleeding after menopause, or if you might be pregnant.
