Hi I am a 36 year old female and have undiagnosed blood traces in urine since a week. All reports normal: urine routine, urine culture, blood routine, ultrasound shows thick uretus wall, ovaries look ok, physical internal examination looks ok. I have been taking thyroid Medication 25mg since last 45 days. There is occasional blood in urine like strings and clots but no period. Not pregnant. Mild pain and fullness in abdomen.
