Birth Control
"Very good in preventing pregnancy. I have had Nexplanon for 18 months. However, it is TERRIBLE for me I have since gained 40 pounds! All within the first 6 months. I was a size 9 when I got this now am about a 12. I am having it removed in two weeks. Mind you that I had a really nice body and now am pushing the scale at 199lbs! I have learned my lesson!"
