Thanks for all these additional details.
I am sorry to hear about your problems.
Well, possible reasons for such traces of blood in urine are-
1)Urinary tract infection.
2)Kidney or bladder stones.
Here bladder infection is the most common cause at your age.
A high fluid intake is essential. You should drink cranberry juice. You should avoid caffeine and alcohol.
From my clinical experience, I am pretty sure that it is not related with any serious issue. No need to get panic.
You may need further tests-
-Urine culture test,
-Ultrasound of lower abdomen.
These tests would be diagnostic, and help in making precise diagnose.
Based upon the type of infection, antibiotics will be advised.
Please don't worry, it is not related with any serious issue.
Please consult your doctor for clinical checkup and get appropriate management.
I hope this helps.
