Burning sensation during urination in early pregnancy

Urinary tract infections (UTIs), also known as bladder infections, are the most common type of bacterial infection diagnosed today, according to research published in the American Journal of Medicine. Roughly 31 percent of pregnant women will have either a symptomatic or an asymptomatic (without symptoms) UTI during pregnancy, research suggests. UTIs occur when bacteria enters into the usually sterile urinary tract and multiplies, causing painful urination and other symptoms. Certain factors during pregnancy make this occurrence more likely to happen. Here’s what you need to know to keep you and your baby healthy.

Why Are UTIs Common in Pregnant Women?

When you’re pregnant, the anatomy of your urinary tract actually changes. For instance, your kidneys become larger and your growing uterus can compress your ureters and bladder. Because of this compression, fully emptying your bladder during pregnancy becomes more difficult. In addition, your progesterone and estrogen levels increase during pregnancy, which can weaken your bladder and ureters. Pregnancy also alters the makeup of your urine, reducing the acidity and increasing the amount of protein, hormones, and sugar in your urine. That excess sugar, for one, can encourage bacterial growth. All of the above contribute to a heightened chance of developing a UTI in pregnancy. And that is why it’s recommended that all pregnant women receive a urinalysis and urine culture at 12 to 16 weeks or during the first prenatal visit.

UTIs by Pregnancy Trimester

Your risk of UTI goes up beginning at week 6 of your pregnancy; the chances you’ll have a UTI vary by trimester.

First Trimester

About 41 percent of UTIs are diagnosed during the first trimester. Because getting a UTI during the first trimester is so common, the U.S. Preventive Services Task Force recommends that your healthcare provider obtain a urinalysis and urine culture at your first prenatal visit. That recommendation holds whether you present with UTI symptoms or not.

Second Trimester

According to the Centers for Disease Control and Prevention, about half as many pregnant women are diagnosed with a UTI during their second trimester compared with the first trimester.

Third Trimester

Compared with the second trimester, the number of women who experience a UTI during the third trimester is almost halved. However, 80 to 90 percent of acute kidney infections in pregnancy (many caused by the progression of an untreated UTI) occur in the second and third trimesters, according to research published in the Archives of Medical Science. Thus, it’s recommended to do a repeat urine culture during the third trimester, too.

Common UTI Symptoms in Pregnant Women

“While mildly painful urination during pregnancy can often mean a yeast infection, not a UTI, it’s always best to see your healthcare provider if you experience any symptoms,” says Heather Bartos, MD, an ob-gyn in Cross Roads, Texas. After all, research suggests that about 18 percent of UTIs that occur during pregnancy are symptomatic UTIs, meaning the telltale UTI signs and symptoms are present:

  • Strong and frequent urge to use the bathroom
  • Burning while urinating
  • Regularly passing only small amounts of urine
  • Cloudy, red, pink or cola-colored urine
  • Foul-smelling urine
  • Pelvic pain, usually in the center of the pelvis

In pregnancy, women are also more susceptible to asymptomatic UTIs, meaning you have significant bacteria in your urine but your urinary tract is free of signs and symptoms. Experiencing no symptoms, however, does not mean that asymptomatic UTIs are benign. “An asymptomatic UTI can lead to a symptomatic UTI or even a kidney infection,” says Dr. Bartos. In fact, research shows that if asymptomatic UTIs are left untreated, 30 percent of pregnant women will go on to develop a symptomatic UTI, and half of those women will eventually be diagnosed with acute pyelonephritis (a kidney infection). Up to 23 percent will have a kidney infection recurrence during the same pregnancy. It’s important to note that classic UTI signs, like frequent and painful urination, may or may not occur with a kidney infection. Here, some signs to look out for:

Typical Signs of a Symptomatic UTI

  • High-grade fever
  • Chills and rigors (sudden feeling of cold with shivering)
  • Headache
  • Nausea or vomiting
  • Lower back pain
  • Flank pain (often right side)
  • Possible reduced urine output

Are UTIs Dangerous During Pregnancy?

“UTIs can rapidly progress to a kidney infection in pregnancy, which can be much more dangerous than a kidney infection in nonpregnant women,” says Bartos. “Severe infections can lead to respiratory problems and sepsis, which can then lead to preterm labor or even the need to urgently deliver the baby.” Beyond a kidney infection, simply having a UTI during pregnancy appears to possibly be a contributing factor to low birth weight. Women who have a UTI in pregnancy also have a 1.31-fold higher risk of developing preeclampsia, a pregnancy complication characterized by high blood pressure, according to a meta-analysis published in September 2018 in the journal Medicine. It’s thought that a UTI may alter a pregnant woman’s inflammatory response, which can spur preeclampsia.

Can Having a UTI While Pregnant Hurt the Baby?

Possibly. “A UTI itself doesn’t hurt the baby directly,” says Bartos. “It’s the failure to treat a UTI that can cause things like preterm birth or, rarely, infection of the amniotic sac.” For example, research published in American Family Physician shows that treating pregnant women who have asymptomatic UTIs decreases the incidence of preterm birth and low-birth-weight infants. That’s why screening and prompt treatment are important.

Can a UTI Cause Contractions During Pregnancy?

Urinary tract infections are not associated with preterm labor, according to research published in the Journal of the Chinese Medical Association. However, if a urinary tract infection is left untreated, it can progress to a kidney infection. And a kidney infection (pyelonephritis) during pregnancy can modestly increase your chances of early contractions and delivery. Research published in the American Journal of Obstetrics & Gynecology notes that women diagnosed with acute pyelonephritis in pregnancy have a 10.3 percent chance of preterm delivery compared with the 7.9 percent chance among women without a kidney infection during pregnancy.

Do UTIs Differ by Trimester?

At week 6, UTI risk starts to go up, with two-fifths of UTIs occurring during the first trimester. Because of the likelihood of getting a UTI during the first trimester, the U.S. Preventive Services Task Force recommends that pregnant women have a urinalysis and urine culture at their first prenatal visit — whether they have UTI symptoms or not. In the second trimester, about half as many pregnant women are diagnosed with a UTI as in the first trimester, according to the Centers for Disease Control and Prevention, and that number is almost halved again for the third trimester. However, 80 to 90 percent of acute kidney infections in pregnancy (many caused by the progression of an untreated UTI) occur in the second and third trimesters, according to data published in the Archives of Medical Science, so pregnant women should have a repeat urine culture during the third trimester.

What Are Pregnancy-Safe UTI Treatment Options?

How do you treat a UTI when pregnant? It’s similar to how you treat a UTI when not pregnant — with a few key differences. A short-course of antibiotics is the standard treatment for asymptomatic and symptomatic urinary tract infections that occur during pregnancy. There are, however, two important contrasts in treating UTIs in pregnant women versus nonpregnant women. First, asymptomatic UTIs diagnosed during the first trimester are treated with antibiotics, whereas nonpregnant women’s infections are often not treated in this manner. (Outside of pregnancy, asymptomatic bacteriuria is usually not treated with antibiotics.) Also, the preferred antibiotic drugs used to treat UTI in pregnancy often differ than what would be used while not pregnant. For instance, the following antibiotics have not been associated with any birth defects, thus are likely safe to use at any point during pregnancy:

  • Penicillins Amoxicillin, ampicillin, and augmentin are in this group.
  • Erythromycin Some of the brand names include Ery-Tab, Akne-Mycin, E.E.S. Eryc, and Pediamycin.
  • Cephalosporins Keflex (cephalexin) is a cephalosporin.

UTI history and resistance patterns must be considered before prescribing any of these drugs.

Because certain antibiotics pose a potential risk for birth defects (anencephaly, heart defects, and cleft palate) when taken during the first trimester, they are only considered a first-line treatment for UTIs occurring during the second and third trimesters, according to the American College of Obstetricians and Gynecologists. Prescribing the antibiotics listed below during the first trimester is considered appropriate only when no other suitable alternative treatments are available:

  • Nitrofurantoin Macrobid, Furadantin, and Macrodantin are in this category.
  • Sulfonamides Bactrim (trimethoprim-sulfamethoxazole) is part of this class.

Be sure to double-check what your healthcare provider is prescribing, since despite the warnings, nitrofurantoin remains the most frequently prescribed antibiotic during the first trimester.

Is it normal to feel like you have a UTI in early pregnancy?

Early in your pregnancy — especially in the first trimester — you may notice some signs that could point to a UTI. These include fatigue, frequent urination, back pain, and nausea. Bad cramps during early pregnancy can also feel similar to the cramps you'd have with an infection.

Does it hurt to pee in the beginning of pregnancy?

It's normal to feel some pressure or pain in or near the bladder at some point during pregnancy. For some women, it's merely due to a growing uterus and will subside without needing further treatment. However, it sometimes occurs due to a urinary infection (UTI) or urinary stasis.
