I've been having to go pee a lot, stomach feels blowed, dark drown discharge has been going on for 3 days already what's going on?

UTI vs vaginosis: See your gyn doctor. Get urine tested and a pelvic check up. Your question is rather vague so hard to decide whether it's primarily a bladder problem or vaginal. Hope it helps.

Urinary Infection: Urinating frequently and change in the color of the urine can be something as simple as a urine infection, especially for a child still in diapers or learning to potty train. The best way to sort this out is for a doctor to get a urine sample and look at it under the microscope
