I want you to have two attempts in the fertile window. So far (and please correct me if I have this wrong) you have had one. So yes, I want you to BD again tonight.
So far, we have yesterday (which we will call our E4d attempt) and today (OPK attempt) Then don't have another attempt until you are 4 days out from the first attempt. Have an attempt 4 days after the first attempt, then 4 days after that, and lather, rinse, repeat until you get AF or a BFP whichever comes first.
