Blood in Urine

From the time of presence of blood in ur urine,be it only at the beginning, or through out the whole or only presence at the end of ur micturition, you can have an idea of your problem without getting panic.
Over dehydration too can make your urine become dark and unpleasant so always stay hydrated to prevent any sort of problem especially stone formation.

Usually blood in urine associated with pain is due to stone and urinary  infection.
Painless blood mixed urine is usually  due to polycystic kidney disease,due to hypertension,tumour of any part of kidney and etc.
So if you see blood in your urine,don't get panic,just go and see your doctor.

Stay blessed.
