hi, you did not mention if you had any urinary symptoms like burning, frequency, urgency or fever
. These indicate urinary infection. Blood and while cells in urine can be due to contamination by vaginal secretions into urine sample while collecting. the cramps can be due to clots in the uterus
or associated inflammation. You should consult your gp or a gynecologist for the same. I would suggest a sonography
of pelvis as well as KUB region, but let your doctor decide. Take care.
