Help - Smiley Face - when to BD??

Question

So I got my positive smiley face this morning about 6am and I'm now off to work and won't be back until around 9.00pm ... We haven't managed to BD so far this fertile window has work has been so full on! Do I still have a chance if I BD tonight? 
I'm CD 11 with around 28 day cycles.

Last month I got my smiley face on CD11 and none on CD 12 ... I'm new to this so all help appreciated! TIA

Answer
