The short explanation
Yes, please take her to hospital today. Fever with burning urine and back pain in pregnancy can be a kidney infection, which is more common in pregnancy and can become serious quickly. It can also trigger early labour. It usually needs prompt treatment, sometimes in hospital, with antibiotics chosen to be suitable in pregnancy. At the hospital they will check her temperature, pulse and blood pressure, test her urine and blood, and check the baby's heartbeat. Getting treatment early usually makes recovery faster and safer.
What depends on your situation
The parts of this that change from woman to woman. Uncertainty is stated, not hidden.
- Urine infections are common in pregnancy because hormones and the growing womb slow the flow of urine.
- Drinking enough water and not holding urine for long helps prevent them.
- If she has had urine infections before, tell the doctor; a urine culture test may be done to choose the right treatment.
- Take her antenatal card and any recent urine reports along.
What this answer cannot determine
The boundary of online education. These need a clinician who can see you.
- This cannot tell you whether she has a kidney infection. Only tests and an examination at the hospital can show that.
Questions for your clinician
Take these with you. You can add any of them to an appointment card.
- Is this a urine infection or a kidney infection?
- Is the baby's heartbeat normal, and are there any signs of early labour?
- Does she need to stay in hospital for treatment?
- Will her urine be tested again after treatment?
When to seek help
Clinician-approved guidance for this topic. When in doubt, being seen is never the wrong choice.
Emergency — call 112 now
- Call 112 or go to the nearest emergency department now if she is shivering badly, vomiting and cannot keep fluids down, confused, breathless, has regular contractions, or the baby moves less.
