The short explanation
The pill can cause light bleeding between periods, especially in the first few months, after missed pills, or with some types of pill. It can also make an area of softer cells on the cervix, called an ectropion, more likely, and these cells can bleed easily after sex. However, bleeding after sex can also come from infections such as chlamydia, cervical polyps, or cervical changes that need checking. Because the pill does not protect against infections, and because some causes need treatment, it is worth having an examination if bleeding after sex happens more than once.
What depends on your situation
The parts of this that change from woman to woman. Uncertainty is stated, not hidden.
- The doctor may look at your cervix with a speculum, take swabs for infection, and check whether cervical screening is due.
- If you missed pills recently, mention it, along with any chance of pregnancy.
- If the bleeding is due to an ectropion, it often does not need treatment unless it is troublesome.
What this answer cannot determine
The boundary of online education. These need a clinician who can see you.
- This answer cannot tell what is causing your bleeding. An examination is needed.
