I've been on depo since January 2015, I haven't had much problems with it until recently. I got my needle at the end of august (not close to be getting my next one) and I've been spotting off and on basically since I got it.. I spot more when I'm moving, I work for 5 hours and I spot toonie size, almost every time I go for a walk even. If I get anxious or stressed out a little bit it happens too.. tmi but the blood usually ranges from really red to brown.. I just want to know what your thoughts are should I be concerned or is this "normal"?
