Did I miss the window?

My intention was to follow the Sperm Meets Egg plan this month — BD every other day and then have sex three days in a row once you get a positive OPK. (We’ve never had an issue with having plenty of sex in my fertile window, so I thought we would try the less is more approach.) Due to too much going on Friday, we weren’t able to BD when I got my positive OPK. We BD’d the next two mornings, but I’m afraid we missed the window! What do you think?
