Nexaplanon birth control

Did you have the 3 months of irregular periods that they say will happen after getting the implant? Or did you just stay having no period for the full 3 years after getting it? My dr told me I would have 3 months of irregular periods but my period has not shown up yet. I'm afraid I'm either pregnant (to early to tell right now) or my period just won't show up (which is fine with me😛)
