Am I out?

The last time we had sex was Tuesday night. I got my peak OPK today, and I'm hoping we can have sex tonight, but he's working late. Is all hope lost for this month? I feel like it is.

Edit: Thank you so much ladies for the encouragement! Hubby is home and we just finished BDing a little while ago. Here's hoping! And to those of you still ttc, good luck to you, too!
