If the urine tests are normal then the source of bleeding is unlikely from the urinary tract
Fresh blood is mostly from the lower GI tract. Because it is always following defecation.
It may be due to hemorrhoids or fissure in ano
or due to hard stools.
You need a Per rectal examination
to arrive at a diagnosis.
The second source of bleed may be from your genital tract.
You need an ultrasound of the abdomen and a Gynecologist consultation.
