AF Due 12/11. 26 yrs old ttc since August

Alyssa • Ttc #1 since August 2015 // 7 IUIs = all BFN // May 18’ Fresh IVF = Chemical // June FET = 👶🏻
I have long cycles.. 40-42 days. TTC since August. Hoping we did it this month! This was my first month tracking bbt. I've been using opks for lh surge and was nervous w long cycles that I might not actually ovulate even tho I get positive opks. I think the temp should confirm that I am ovulating tho!! 
AF is due 12/11. Hoping she doesn't come so I can get the best Christmas present ever! 
Anyone else similar?
