The short explanation
Light bleeding after sex is quite common and often has a simple cause, but it is worth getting checked if it keeps happening. Possible reasons include dryness or small tears at the vaginal opening, an area on the cervix called an ectropion where softer cells bleed easily, infections such as chlamydia, and cervical polyps. Less often it can be linked to changes on the cervix that need treatment. Because some of these causes are easy to treat and a few need early attention, doctors recommend a check-up for repeated bleeding after sex rather than waiting.
What depends on your situation
The parts of this that change from woman to woman. Uncertainty is stated, not hidden.
- The doctor will usually ask when the bleeding happens, whether there is pain, discharge or a bad smell, and whether you use contraception. A gentle speculum examination lets them look at the cervix, and swabs can test for infection.
- If you are 25 or older and have not had cervical screening, it may be offered.
- Not enough arousal or lubrication can cause small tears and pain. Talking with your husband and going more slowly often helps. You can ask for a woman doctor.
What this answer cannot determine
The boundary of online education. These need a clinician who can see you.
- This answer cannot tell why you are bleeding after sex. An examination, and sometimes tests, are needed to find the cause.
