I am meant to be having the implant fitted because the doctor kept telling me it was better then the pill. I don't really know much about it and have been reading reviews about it. All have which been negative and talk about depressive moods and weight gain. I have had weight issues in the past and I'm at a weight which I am comfortable with and I have suffered from depression. I am worried that the implant may make it worse. What do you think I should do?
