2weeks late

First off I have been hormone free for over two years my periods are good then get crazy then good and crazy again... I've been on hormones to jump start my period a few months ago and thyroid meds a well. I've been on time and my cylcle has been good but now I'm late. Took a preg test BFN. Started a period which was dark to begin with and by the end of the day it was super light the next day it was little to none now it has completely stopped... I just need a little advice or if someone can share their experience. My body totally sucks right now. We are not TTC at the moment but a baby would hurt either. Some feed back please.
