A urinary tract infection during pregnancy is more common than many women realise, and it matters more, too. Because of the natural changes pregnancy brings to the urinary system, infections can develop more quickly and carry a higher risk of complications if left untreated. Knowing what to look out for means you can act promptly and get the right support.
Why Are UTIs More Common During Pregnancy?
Pregnancy increases susceptibility to urinary tract infections for several reasons. As the uterus grows, it places pressure on the bladder, making it harder to empty fully. Hormonal changes also cause the ureters (the tubes connecting the kidneys and bladder) to relax and widen, which slows the flow of urine and gives bacteria more opportunity to multiply.
These are among the most common causes of urinary tract issues during pregnancy and explain why your midwife or GP will routinely test your urine at antenatal appointments.
What Are the Signs of a UTI During Pregnancy?
The urine infection symptoms in pregnancy are often similar to those outside of it, but some women experience few or no symptoms at all, which is why testing remains important throughout. Common signs of a UTI in females during pregnancy include:
- A burning or stinging sensation when passing urine
- Needing to urinate more frequently or urgently than usual
- Passing only small amounts of urine despite the urge
- Cloudy, dark, or strong-smelling urine
- Pain or discomfort in the lower abdomen or pelvis
- A feeling that the bladder has not fully emptied
If any of these symptoms are present, contact your midwife, GP, or pharmacist promptly. Do not wait to see if symptoms improve on their own.
When Might a UTI Infection in Pregnancy Become More Serious?
A UTI infection in pregnancy that spreads to the kidneys (known as pyelonephritis) requires urgent medical attention. Symptoms that suggest the infection may have progressed include:
- A high temperature or fever
- Shivering or chills
- Pain in the lower back or sides (flank pain)
- Nausea or vomiting
- Feeling generally unwell
If you experience any of these, seek medical help the same day. These symptoms warrant immediate assessment rather than a routine appointment.
What Is Asymptomatic Bacteriuria?
Not every UTI in pregnancy comes with obvious symptoms. Asymptomatic bacteriuria refers to a significant presence of bacteria in the urine without any noticeable signs. In pregnancy, this condition is associated with an increased risk of developing a kidney infection if untreated, which is why routine urine testing at antenatal visits is so important.
The NHS recommends that pregnant women are screened for bacteriuria early in pregnancy. If detected, it is typically treated with antibiotics prescribed by your GP or midwife.
What Should You Do If You Suspect a UTI During Pregnancy?
If you notice any signs of a urinary tract infection in pregnancy, the most important step is to speak to a healthcare professional as soon as possible. Do not self-treat or delay. Your GP, midwife, or a GPhC-registered pharmacist can advise on the appropriate next steps.
Treatment will typically involve a course of antibiotics that are considered safe to use during pregnancy. The specific antibiotic and duration will depend on the type of bacteria identified and the stage of your pregnancy. Always complete the full course, even if you feel better sooner.
Practical Steps That May Help Reduce Your Risk
Whilst there is no guaranteed way to prevent a UTI, the following measures are widely recommended as part of good urinary health during pregnancy:
- Drink plenty of water throughout the day to help flush the urinary tract
- Urinate regularly and do not hold on when you feel the urge
- Wipe from front to back after using the toilet
- Urinate after sexual intercourse
- Avoid perfumed bath products or feminine hygiene sprays around the genital area
These steps are not a substitute for medical assessment if symptoms arise, but they form sensible habits throughout pregnancy.

Frequently Asked Questions (FAQ’s)
Can a UTI harm my baby during pregnancy?
An untreated UTI, particularly one that develops into a kidney infection, has been associated with risks during pregnancy, including preterm labour. This is why prompt treatment is important. With timely diagnosis and appropriate treatment prescribed by a healthcare professional, UTIs can usually be managed safely.
How quickly should I seek help if I think I have a UTI in pregnancy?
You should contact your GP, midwife, or pharmacist on the same day you notice symptoms. Do not wait overnight or over a weekend if you are concerned. If you develop a high temperature, back pain, or feel very unwell, seek urgent care.
Are antibiotics safe to take for a UTI during pregnancy?
Some antibiotics are considered safe to use in pregnancy, though the choice of antibiotic may vary depending on your stage of pregnancy and the bacteria identified. Your prescriber will choose the most appropriate treatment. Never take antibiotics that have not been prescribed for your current condition.
Will my midwife test me for a UTI even if I have no symptoms?
Yes. Routine urine testing is a standard part of antenatal care in the UK. This is specifically to detect asymptomatic bacteriuria, which has no obvious symptoms but can lead to complications if left untreated during pregnancy.
