I have been using implanon for 8 months and I ovulated this month, I've been cramping and feeling Nauseated, I had implantation bleeding today and a faint positive test. The lumps on my boobs are getting bigger, I've had lots of creamy white discharge and my ovarie area is growing already. I look pregnant, and I would only be 5 weeks tomorrow if I am. I knew I was pregnant as soon as I ovulated. This has caused complications to my relationship and implanon is supposed to be 99.9%. :(
