I had blood in my urine could it be that i'm taking calcium? i also had pain on my right upper back i was told it was kidney stone. is this true?

Is that so?: If an imaging study was performed that showed you have a kidney stone, then that's probably why you have the blood in your urine. If there's no imaging study, you don't know if it's a kidney stone or not, and getting imaged would probably be worthwhile. Why are you taking calcium? I can't recommend it as a general 'women's health' measure especially if there's a question of nephrolithiasis.
