AF due in 6 days

Lauren
I have a metallic taste in my mouth felt what I can only describe as implantation cramps during this past week Decided to prematurely talk a pregnancy test of course it was BFN but still sad I had a mc in April I guess I was just hoping bc I had symptoms it would be positive Trying not to get my hopes up but I know I just need to be patient Any thoughts from anyone greatly appreciated ... The metallic taste had been happening for days taste like I'm chewing On pennies
