Urinary tract infection or chronic bladder infection is one of the most common causes of the appearance of blood in urine. Since, pregnant women are more at risk of contracting this bacterial infection, it is common in pregnant women. As the uterus grows, its increased weight can block the drainage of urine from the bladder, thus causing infection which leads to the presence of blood or mucus in the urine.
persistent blood in urine during pregnancy must be diagnosed and treated as soon as possible. For the diagnosis, a thorough physical examination along with an assessment using a urine culture must be done in laboratory settings. The first test performed in the emergency department or medical office, is a dipstick test where a strip of chemically treated paper is dipped into a cup containing a sample of your urine. The paper will show different colors to indicate the presence of blood, protein, glucose, or infection in the urine. This is followed by a formal urinalysis where the urine is examined under a microscope to look for red blood cells and white blood cells, which signify infection. For detecting kidney stones, an ultrasound or a single shot x-ray must be done. In the majority of the cases antibiotics suited for pregnancy are given for treating the condition.
I would recommend you consult with a nephrologist immediately and take urine analysis and urine culture test, to identify the causative organism and start on appropriate antibiotic.
Hope this helps. feel free to ask for further question.
