I have been on depo for 9 years. I have never really bleed while on it except I will spot like a week before my shot is due and when I pee here and there but not even enough for panty liners. And that blood was generally brown in color. Id say the past year I ha e been spotting more often still n9t every month. But now with my last shot a month and half ago I have been bleeding bright red blood for almost 2 weeks and clot some when I pee only. I know that spotting and constent bleeding is normal but I have not had these symptoms for most the years I been on depo
