Thanks for the query.
Blood in urine could be due to faulty collection of urine sample during menstruation(mixing of menstrual blood during collection of urine sample).
I recommend you to repeat your urine microscopy once your periods stop.
can cause pelvic pain
and heavy menstrual bleeding.
Definitive diagnosis is by MRI
Treatment depends on your willingness to conceive and severity of symptoms.
Do visit your doctor to discuss the treatment protocols.
Hope this helps.
