Urinary Tract Infections (UTI's) – Pain when urinating, abdominal discomfort, blood in your urine, and a frequent urge to urinate with little production, are all signs of UTI's. UTI's are easier for women to get during pregnancy because important muscles in your urinary tract relax and slow the flow of urine. When this happens, bacteria have a better chance of growing, leading to an infection. If you suspect you may have a urinary tract infection, it is very important to report your symptoms to your physician because untreated UTI's can lead to complications during pregnancy.
