The short explanation
Yes — bleeding between periods, or after sex, is worth having looked at even when it is light and even when it settles. Most causes turn out to be minor, but it is one of the few gynaecological symptoms that should always be assessed rather than watched, because a small number of causes are serious and are far more treatable when found early.
What depends on your situation
The parts of this that change from woman to woman. Uncertainty is stated, not hidden.
- Common explanations include a cervical polyp or ectropion, an infection such as chlamydia, the first few months on a new hormonal contraceptive, a missed pill, fibroids, and in the years around menopause, the cycle changing. Spotting at mid-cycle around ovulation happens to some women every month.
- Bleeding after sex specifically points towards the cervix, which is why an examination usually forms part of the assessment even when the bleeding seems trivial.
- Cervical screening is not the same as an examination for symptoms. If you have symptoms, you need to be seen about them now, whatever your screening history says.
- Any bleeding at all after menopause — even one episode, even a smear of blood — is assessed urgently. That is a firm rule rather than a cautious suggestion.
What this answer cannot determine
The boundary of online education. These need a clinician who can see you.
- This cannot tell you what is causing your bleeding, and it cannot reassure you that it is nothing. Only an examination can start to do that.
- This is not a cancer risk assessment. Nothing written here can estimate your personal risk of anything.
- This explanation was written by AskHer's editorial team from the guidance listed under Sources. A clinician registered in India has not signed this version off yet — that is why no clinical reviewer is named at the foot of this page, and it is why nothing here is a diagnosis.
Questions for your clinician
Take these with you. You can add any of them to an appointment card.
- This is when the bleeding happens and how much it is. What do you think it is?
- Do you need to examine my cervix, and what will that involve?
- Should I be tested for an infection at the same time?
- Could my contraception be causing this?
- Is this something that needs following up, and when?
When to seek help

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.
