Highly fertile, no show of OV...Could use some help!

My fertile window started last week on the 19th and on Tuesday, I received a flashing smiley (highly fertile) using Clear Blue Advanced Digital. I've had flashing smileys for 6 days now. I also tried the opk stick just now and here it is. My AF is due on the 8th, but no signs of ovulation yet. We've been BDing a lot 😍, but I want to make sure I don't miss my window. Any advice? Has this happened to you all? Do I still have a good chance this month?
