I had used the depo provera injection in the last for about four years. I never had a period during that time frame. I switched to the nuva ring for a year, and began back on the depo injection in January 2015. The first and second injection were fine, with the exception of spotting one week before the third injection was due. I had my most recent injection on October 7,2015. November 4 I began with light dark brown( old blood) spotting. This spotting has continued for nearly four weeks now, and occurs about six days a week- for a few hours a day. I am not pregnant.I've also managed to gain ten pounds since the last shot and recently have been battling acne and high blood pressjre... I know these are all side affects. But considering my history with the injection, I'm a bit fusterated with this recent experience. Is this normal?
