Nexplanon/Implanon

Shelby
Hey everyone, I have had my in the arm birth control (nexplanon) since April. Before this I was on the depo shot forb2 years. I experienced steady weight gain on the depo and I'm afraid it might be following with the implant too. Has anyone else had any weight gain with it? They say it isn't a common side effect like it is with depo. I also haven't gotten a period or any kind of bleeding with it either... is that normal?
