Did we miss it?

According to FF and Glow I O'd on CD 17, DH and I BD'd on CDs 12, 14, 16, 18... So what's your opinion on my chances since we didn't BD on the actual day I O'd?? We are on month 9 of trying and this is the first month I convinced my DH to have sex more than 2xs during my "green" days without the pressure totally freaking him out.
