Nexplanon

Alright, so I'm super concerned about my birth control method. I got the Nexplanon implant in my arm about a year ago, and maybe a few months ago I stopped getting my period. I'm just curious if it's normal or not? Cuz the only other form of bc I've used was the pill and I was never very good at taking it because I would forget it all the time. So ladies, help me out. Tell me your experiences with your birth control methods please
