Clear blue advanced digital and flashing smiley face

Ana

Hi! I've been TTC for almost a year and this is my first time using an ovulation test. My average cycle length is between 29-30 days, I started using clear blue advanced digital test on cd10. I got a black circle on the first day of testing and then I got 8 flashing smiley's in a row. haven't seen a solid smiley yet. should I keep testing? what doe's this mean? did anyone had the same situation?
