birth control
"After I had my son I knew I didn't want to have anymore children for a while but I wasn't willing to do anything  permanent. I thought this was perfect for me. I was so wrong. I got the implant six weeks after having my son. At that time I had lost all of the baby weight and then some. I was 130lbs then. Now nine months later I am 177. I exercise everyday and I limit my calories. I've never had an issue losing weight. it has always been very easy to lose and keep off extra pounds. Now I can't lose weight no matter how hard I try. My self esteem is at an all time low. I don't even go out in public unless I absolutely have to. 
It is very effective as birth control but it's not worth the side effects"
