Blood in Urine & Delayed Period: Possible Causes & When to See a Doctor

Question
The first day of my last period was 26th Feb and it is now 17th April.  I have blood in my urine.  Could Cystitis cause a late period?

Answer
cystitis can't cause a late period.  It is often hard to tell if blood in the urine is from "period contamination" but if you truly have blood in the urine, you should be evaluated for cystitis and other potentially more serious urinary tract conditions.... that is worth a trip to the doctor for re-evaluation.
