abnormal uterine bleeding
"I got my first depo shot September 26, 2016. I was due December 25, 2016 but I didn't go back because I noticed it made me depressed   I wasn't sexually active so what was the point. 2 weeks after I was due I started a light period and spotting and it's been like that for almost 3 weeks. I'm so frustrated I just want this out of my system. I do not recommend the shot."
