If you find that you have abdominal pain and your symptoms begin to worsen, you should contact your doctor immediately, as this could be a sign that the infection is spreading. Pregnant women should be especially careful. Symptoms of urinary tract infections aren’t always visible or noticeable right away, but here are some tell-tale signs that you may have one. • A strong, persistent urge to urinate. • A burning sensation when urinating. • Passing frequent, small amounts of urine. • Urine that appears cloudy. • Urine that appears bright pink or red could be a sign of blood in your urine.  • Strong-smelling urine. • For women — pelvic pain in the center of the pelvis and around the pubic bone. If you have been experiencing any of the symptoms mentioned above, contact your doctor and go in for a check-up to receive a proper diagnosis and appropriate treatment.
