Looking for guidence

So here's the scoop. I am right on target for today to be my O day and I am very anxious to have a christmas BFP. This week me and DH BD on the 14 th and then again early this morning so on the 18/19th I guess. Well i had to get up for work very early at 4 am and I had EWCM so I most definitely must be Oing today. My question is do you think we should try to get another session in tonight to make the chances better or do you think we will be out of our window? What would you ladies do?
