Did you fall hard??? If kumain ka ng watermelon kahapon i don't see any connections para maging reason xa na maging bloody colored ang urine mo today, for sure nailabas mo na yan kahapon. I think you need to be check po, the probability na ang cause ng bloody urine mo is your fall, is quite high. Para maging at ease ka din po. Have a Checkup. God bless.
