Just need help!

So, according to glow my period is due on Thursday December 14th. I have taken 3 test one with a very faint line, but blue dye and then one blue dye with nothing and one FRER where I saw absolutely nothing! I mean stark white :( I don't feel like I'm about to start my period, but I'm not sure. am I out? should I retest on the day of AF? Who all has gotten negative after negative and then ended up getting a positive? I just have this feeling, not too many symptoms just this FEELING! I know I probably sound crazy, but please leave your opinions.. Please tell me I'm not out!
