I am 32, (5ft 6in, 8 stone) with 2 children and have had the contraceptive implant for well over a year. Since having it fitted I have suffered from mood swings, periods of extreme sadness, feelings of worthlessness and most of the time feel completely detached from the world around me. In between these periods I have felt extremely happy and excited about the future. It is probably also worth mentioning that just before I had the implant fitted my youngest son was diagnosed with autism and my husband lost his job this caused a huge amount of stress and could be the cause for my depression. I know my Grandma suffered with depression at the end of her life and my Mum has periods of it. I also suffered from depression as a child (from about age 10 to 15) and then I had post natal depression after my first child. Could the implant be the cause or could I be bi polar? I have read a lot about the condition and seem to tick a lot of boxes.
