The short explanation
Pink or red urine needs to be checked, even without pain, though the cause is often not serious. Some foods, such as beetroot, and some medicines can colour urine pink. Blood can come from a urine infection, a kidney stone, vigorous exercise, or occasionally from the bladder or kidneys themselves. It can also be blood from the vagina mixing with urine around the time of a period. Because painless blood in the urine can sometimes come from a problem that needs early attention, doctors prefer to test rather than wait and see.
What depends on your situation
The parts of this that change from woman to woman. Uncertainty is stated, not hidden.
- Your age, whether you smoke, any recent infection or injury, kidney stones in the past, blood-thinning medicines, and whether this happens again all change what a clinician will look for. A urine test confirms whether there is actually blood, and further tests may include a culture, blood tests and an ultrasound.
- If the colour cleared after eating beetroot or another strongly coloured food, mention that too.
What this answer cannot determine
The boundary of online education. These need a clinician who can see you.
- This answer cannot say where the colour comes from or whether it is blood. Only a urine test and a clinician's assessment can do that.
Questions for your clinician
Take these with you. You can add any of them to an appointment card.
- Is there actually blood in my urine?
- Do I need a urine culture, blood tests or a scan?
- Could any food or medicine I take explain the colour?
- If the test is normal, should it be repeated?
When to seek help
Clinician-approved guidance for this topic. When in doubt, being seen is never the wrong choice.
Get help the same day
- Get care the same day if you pass clots, cannot pass urine, have severe pain, or have fever with back pain.
Book an appointment soon
- See a clinician within a few days for any unexplained pink or red urine, even if it has stopped.

Did this answer your question?
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.
Saving, following up and reporting are all private. Nothing you do on this page is visible to other readers or to the doctor who wrote it, unless you ask a question.
