PLEASE HELP!

Erika-Lynn
I am so confused.. this is my first time using ovulation kits and the darkest line I have had was on 11/30.. and then that's the last time I saw a line. My last period was November 18-21. Did I miss my chance this month? On glow it says my peak day was yesterday(12/09/16) but I have been taking ovulation tests everyday and nothing. I NEED HELP!
