birth control
"I truthfully do not have anything positive to say about this form of birth control. Prior to this birth control, I was one of the lucky ones; I used a generic BC and my periods were 3 days, very light, no cramps, acne, or mood swings. 

I have been on Nexplanon for 11 months I have been on my period almost ever since.  My acne is painful and atrocious. I have way worse and almost unexplained mood swings. As I said, I have nothing positive to say about this BC."
