Blood in urine with small mucus like clumps

Patient: Hi, I’m a 20 year old female. After I finished masturbating, I had a really bad urge to pee. I went to wipe and there was blood. I looked in the toilet and it was pink with small mucus-like clumps of blood. I have no pain, but now i feel the constant urge to pee. I’m sure it was coming from my urethra and no where else. I’m sort of scared.

Symptoms: Blood and small mucus-like clumps in urine, constant urge to urinate
