Urinary tract infections are among the most common health problems during pregnancy. If you have a urinary tract infection during your pregnancy, you will need early treatment. If it's left untreated, it may lead to premature labour. You may not have any symptoms, so your midwife will ask for urine samples to test at your routine appointments. If you do have any symptoms(eg pain or burning when you urinate), it's important that you get advice from your doctor or midwife.
