New to nexplanon implant?

After being on the pill for over five years, I got the nexplanon implant in November 2018, after my period ended. I figured it was more convenient and effective than having an anxiety attack over a missed pill. In December I got my period but this month I’m not getting it? I don’t feel funny or any pregnancy symptoms at all? Has anyone experienced on/off bleeding with this?

My friend said she didn’t get hers for two years and then suddenly got it again so I can tell that it’d be irregular as fuck

Could the dec period have been hormones from my pills still working and now I’m just not gonna get it??? Ahhh I’m new to this HALP
