Why is my lower stomache hurting and I have blood in my urine?

I am assuming you are a woman but your question was under men's health. Sounds like a urinary tract infection. You need to go the Dr. And get antibiotics IF thats what it is . But you need to go now. It could be a kidney infection too. I have had the same thing. It was a urinary tract infection. So please don't put it off you need medicine. Feel Better!!
