opinions on symptoms

Jessica
Hey ladies,
AF is due today and hasn't come yet, though the day is young. 
But I've been feeling a little nausea this morning and have a strange metallic taste in my mouth as well as what is seeming to be excess saliva. 
Also TMI but this morning I had a long bit of cm which while I was weeing just hung there and then dropped before I could touch it but it looked quite sticky and white. 
Am I just hoping too much or could this be legit? 
Took a test and I think I see something but it' very very light.
I'm 14 DPO.
THANKS LADIES
