The same thing happened to me. I had kidney stones and didn't know it. I hated the doctor too, but u need to go. I had the blood thing too, I was peeing blood as well. It could also be a urinary tract infection, which can only be cured with antibiotics. You are doing the right thing though, that's what the docs told me to do, was drink cranberry juice and a ton of water, it helps. Good luck
