Hi and thanks for the query,
Its critical to identify whether this is bleeding or something else. U urine test shall be very necessary. Coupled with a good clinical evaluation and history, it would critical to exclude local lesions, ovulation bleeding, chronic menstrual flow, or other conditions that could mimic blood flow like dyes, drinks or hematuria
. I would be important to know if this is the first time you are experiencing this or not? and whether you took a drug you have never been taking before lately or not.
My advice is you consult your family physician.
Thanks and best regards,
