New to OPK... Am I getting Close?

Brittany • 27. Finally got my BFP after 11 cycles of TTC by using the SMEP, Preseed, and a whole lot of prayers!!
Hey ladies. This is my first month using OPKs. I tested once per day, in the evening, up until CD17. Am I getting closer or am I there yet? 
This is a closer view of today, CD18. 
If I'm not there yet am I close?
