Nexplanon

Hi! I know that girls can sometimes not have their periods while on nexplanon but I couldn't really find a good article on it. When I first got the implant back in May, I had faint spotting for like a month, which is supposed to be an indicator of how the implant will be for you going forward. But then the spotting stopped so I was like cool, I must just have super light periods going forward. But then!! I haven't had my period since the spotting and I honestly thought that was ok cause nexplanon can cause that to happen...but do you not have your period ever???? I mean it's almost April.. anyone else not have their periods for this long ??
