advance clear blue ovulation test question 😰

I'm using advance CB ovulation test and I finally had a flashing smiley face yesterday after testing for about a week. However today when I tested, I got a solid smiley face. My partner and I baby dance yesterday when I got the flashing face and I'll make sure we baby dance today and tomorrow. What I'm worry that since I know had one day of high fertility it won't be enough. Has anyone experience only once day of high fertility and the next day a solid smiley face ?
