In pregnancy you already go to the toilet more than you ever thought possible. So when it starts to burn as well, it is easy to blame the baby and carry on. Many women do exactly that, sometimes for weeks.
Please do not. Being pregnant with a urine infection is common, and it is very treatable. But in pregnancy, an infection that would be a nuisance at other times can climb to the kidneys quickly. It needs a proper test and the right medicine, not a guess.
This guide explains why infections are more common in pregnancy, the signs to watch for, how they are treated safely, and when to come in the same day. Our gynaecology department in Sonipat does the urine tests and the consultation in one visit.
Why pregnancy makes infections more likely
Two changes work together.
First, pregnancy hormones relax the muscles of the urinary tract. The tubes that carry urine from the kidneys to the bladder widen and slow down. Urine moves more lazily, which gives germs time to grow.
Second, the growing womb presses on the bladder. It may not empty fully, and the urine left behind is another place for germs to settle.
The infection you cannot feel
Here is the part many women do not know. Some pregnant women have germs in their urine with no symptoms at all. Doctors call this asymptomatic bacteriuria.
It sounds harmless, but in pregnancy it is not. Left alone, it can lead to a kidney infection, and it has been linked to early labour and a smaller baby. That is why a urine culture is part of the routine tests at your first pregnancy visit. Our guide to your first pregnancy checkup explains the full set.
If the culture finds germs, you will be treated even though you feel well. A repeat culture afterwards checks that the germs have cleared.
Signs of UTI in pregnancy
The common signs of UTI in pregnancy are the same as at any other time:
- Burning or stinging when passing urine
- Needing to go urgently, and passing only a little
- Cloudy, dark or strong-smelling urine
- A dull ache low in the tummy
- Sometimes, a little blood in the urine
The tricky part is that frequent urination is normal in pregnancy. The difference is burning, urgency and a feeling of not finishing. If in doubt, a urine test settles it in a few hours. Our guide to burning during urination describes these symptoms in more detail.
Pregnant with a urine infection and a fever? Come in today
These signs suggest the infection may have reached the kidney:
- Fever or shivering
- Pain in the back or side, below the ribs
- Vomiting or being unable to keep fluids down
- Feeling generally very unwell
- Tightening or pain in the tummy, which may be early contractions
A kidney infection in pregnancy usually needs treatment in hospital, with antibiotics through a drip. Do not wait for the morning. Come in, or go to the nearest hospital.
How it is treated safely
The treatment is an antibiotic. But in pregnancy, the choice matters more than ever. Some antibiotics that are fine at other times are avoided in pregnancy, or at certain stages of it.
That is why we ask for a urine culture. It names the germ and shows which safe antibiotic will kill it. If you are very uncomfortable, your doctor may start a pregnancy-safe antibiotic straight away and adjust it when the culture result arrives.
A few rules:
- Do not take leftover tablets or ones suggested by a chemist. Some are not safe for the baby.
- Finish the course, even when you feel better.
- Drink water steadily through the day.
- Ask before using urine alkaliser syrups. They ease burning but do not cure infection.
At our NABL-accredited laboratory, the current price is ₹150 for a urine routine test and ₹800 for a urine culture, as listed on our tests page. Our general guide to UTI medicine explains why the culture matters.
The ACOG guide to urinary tract infections and the NHS guide to urinary tract infections both stress prompt testing and treatment in pregnancy.
After the infection clears
Most women feel better within two or three days of starting the right medicine. Even so, we ask for a repeat urine culture once the course is finished. In pregnancy we want proof that the germs are gone, not just that the burning has stopped.
If infections keep coming back, your doctor may suggest a small daily dose of a safe antibiotic until delivery. That sounds like a lot of medicine, but it is far gentler than treating a kidney infection in the middle of the third trimester.
Small habits that help
- Drink enough water that your urine stays pale yellow.
- Do not hold urine. Go when you feel the need.
- Lean slightly forward when passing urine, to help the bladder empty fully.
- Wipe from front to back.
- Pass urine soon after sex.
- Wear loose cotton underwear.
These do not replace treatment, but they make the next infection less likely.

Questions mothers-to-be ask us
Can a urine infection harm my baby?
Treated promptly, a bladder infection rarely causes any harm. The risk comes from leaving it untreated, when it can reach the kidneys and, in some cases, bring on early labour. That is why testing and treating early matters.
Are antibiotics safe in pregnancy?
Many are, and your doctor will choose one that is safe for your stage of pregnancy. The risk of an untreated infection is far greater than the risk of a well-chosen antibiotic.
I have no symptoms. Why do I need a urine culture?
Because some women carry germs in their urine without feeling anything. In pregnancy, these silent infections can still climb to the kidneys. A routine culture finds them early.
Can cranberry juice treat a urine infection in pregnancy?
No. It does not cure an infection. It is generally safe to drink, but it is not a replacement for proper treatment.
