It may be possible that the trauma of inserting the catheter may have led to some bleeding. If that is the case, it will heal on its own.
However, I would also evaluate the prostate to exclude any infection or mass. A transrectal ultrasound can be considered, as well as appropriate urine tests.
If the tests remain negative, and the bleeding continues, a cystoscopy can be considered as well.
Followup with your personal physician is essential.
