What do you guys think?

First cycle since starting a couple months ago tracking with opks. Trying for baby 4. Im kicking myself a bit though cos we didnt bd on 9/24 due to husband having a hangover and then going to his moms house to celebrate his birthday and staying there too late. I think i had my peak last night around 930... so app estimating o today. We did bd today before work though. I know chances of pregnancy are on the lower side anyways.... but do we still have a pretty good chance, even if we probably missed the most important day to bd? :/
