peak fertility but no high fertility

I have been using the clear blue advanced opk and yesterday I got the empty circle meaning not fertile. Usually there is a couple days after that that show the fight fertility with the flashing smiley face but mine just went straight from no fertility to peak fertility. Has anyone had this happen to them? I feel like I missed out on a couple days of possibly making a baby 😕. The test say once you get the peak fertility sign you have 12-24 hrs to BD but now I don't know if maybe that started midday yesterday. Feeling frustrated 😔.
