a couple of weeks ago I went in to be checked for pain in my kidneys. i was screened for infection or bladder infection specifically and while i was negative for infection, there was blood in my urine. the following week i started my cycle, which lasts typically 5-6 days. I have been spotting now everyday since it started (November 1st). there is no pain or odor, however, this has only happened to me once before and it was quite some time ago. i am 48 years old and in good health, is there anything that i should be concerned about? could this be the start of menopause?
