I dunno. When I had kidney stones, I had blood in my urine.
I don't mean to be graphic, but it would help to know if you can tell whether the blood is coming out of your urethra or vagina. If it's from the urethra, it could be kidney stones or an urinary tract infection. If the source is vaginal, it could be serious. Could be an STD, or if you've started any medication, that could be it. I'm no expert, but I would get it checked out. Who knows, it could just be a minor infection, but I'd still go to a doctor.
