HELP PLEASE- SO CONFUSED!

Ashley
I am on cycle day 12, and have been using ovulation tests for the past few days- each time being negative! I had a bit of sticky , egg white cm yesterday, and after seeing it , it actually made me test twice cuz I thought for sure it would b positive, and again a Big fat negative! Today I tested negative again! Please someone tell me, is this normal!??? Could I still test positive maybe tomorrow? Really disappointed and confused
