When is your scheduled test? Such info would go a long way in helping to determine whether you need to continue exercise or not.

Take another home test, but this time use the first urination of the day. If you test negative with the first urination (regardless of line intensity), youre good to go.

Drinking fluids is only helpful on the day of the U/A. Drinking a bunch of fluids days or weeks before the U/A is of no help. THC is stored in the fat cells and remain there until the fat cells are burned for energy. Because THC is not water-soluble like other types of drugs, you cannot "wash" or "flush" THC from the fat cells by drinking copius amounts of water. When fat cells burn, the stored THC is metabolized into THCA and released back into the bloodstream, filtered by the kidneys, and deposited into the bladder. The rate in which THCA is filtered from the bloodstream by the kidneys is unaffected by water consumption.

Drinking water only serves to dilute (thin out) the THCA concentration that is present in the bladder. The idea is to thin out that concentration enough to where the urine sample registers below the cutoff thresholds of the drug screen. The diluting phenomena however, is only temporary - once all of the water consumed had all been urinated out, a "dirty" donor would resume testing positive for THC.
