UTI During Pregnancy
The short answer
Urinary tract infections (UTIs) are common during pregnancy, affecting 2-10% of pregnant people. Pregnancy increases UTI risk due to hormonal changes that relax the urinary tract and the growing uterus compressing the ureters. Untreated UTIs during pregnancy can lead to kidney infections and pregnancy complications, so prompt treatment with pregnancy-safe antibiotics is important.
This is one of the most common questions parents ask. Searching for answers means you care.
By Age
What to expect by age
Your provider will screen for bacteria in your urine at your first prenatal visit, even if you have no symptoms, because asymptomatic bacteriuria (bacteria without symptoms) is common and should be treated during pregnancy to prevent kidney infections. Drink plenty of water and urinate frequently.
UTI risk continues throughout pregnancy. Symptoms include burning with urination, frequent urgent need to urinate, cloudy or strong-smelling urine, and pelvic discomfort. Wiping front to back, staying hydrated, emptying your bladder completely, and urinating after intercourse can help prevent UTIs.
UTIs in the third trimester need prompt treatment as they can increase the risk of preterm labor. If you develop symptoms of a kidney infection - high fever, back pain, nausea, or vomiting - seek immediate medical care. Several antibiotics are safe and effective during pregnancy.
What Should You Do?
When to take action
- Frequent urination without pain or burning is normal in pregnancy and not a UTI
- Clear, pale yellow urine without unusual odor
- Burning or pain when urinating
- Urgent frequent need to urinate small amounts with discomfort
- Cloudy, dark, bloody, or foul-smelling urine
- Mild lower abdominal or pelvic discomfort with urinary symptoms
- Fever, chills, back pain (especially on one side), nausea, or vomiting with urinary symptoms - suggesting kidney infection (pyelonephritis)
- Blood in urine with severe pain
- UTI symptoms accompanied by contractions or pelvic pressure before 37 weeks

Related Maternal Concerns
Frequent Urination in Pregnancy
Frequent urination is one of the most common symptoms of pregnancy, affecting nearly all pregnant people. It is caused by hormonal changes, increased blood flow to the kidneys, and the growing uterus pressing on the bladder. It is most noticeable in the first and third trimesters and is usually completely normal.
Yeast Infections During Pregnancy
Yeast infections are more common during pregnancy due to higher estrogen levels and changes in vaginal pH that promote Candida overgrowth. They affect about 1 in 4 pregnant people. While uncomfortable, yeast infections do not harm the baby during pregnancy. Topical antifungal treatments are safe and effective during pregnancy.
Dealing with Abnormal Prenatal Screening Results
An abnormal prenatal screening result can be terrifying, but it is important to understand that screening tests are designed to cast a wide net and have significant false-positive rates. Most people with abnormal screening results go on to have healthy babies after further testing confirms the baby is fine. An abnormal screening is a reason for more information, not a diagnosis.
Pregnancy Over 35 (Advanced Maternal Age)
While pregnancy after 35 carries some increased risks (including chromosomal abnormalities, gestational diabetes, and hypertension), the vast majority of people over 35 have healthy pregnancies and healthy babies. The term "geriatric pregnancy" is outdated and does not reflect reality. With appropriate prenatal care and monitoring, outcomes are excellent.
Amniocentesis Questions and Fears
Amniocentesis is a diagnostic test performed between 15-20 weeks that analyzes amniotic fluid to detect chromosomal conditions and genetic disorders with over 99% accuracy. The risk of pregnancy loss from the procedure is approximately 1 in 500-1,000 when performed by an experienced provider. Understanding the actual risks can help you make an informed decision.
20-Week Anatomy Scan Unexpected Findings
The 20-week anatomy scan checks your baby's major organs, structures, and growth. Most scans are completely normal. When unexpected findings are identified, they range from minor variants that resolve on their own to conditions that need further evaluation. Many findings require nothing more than a follow-up ultrasound to confirm the baby is developing well.
